Also while charge-backs are a negative from the merchants perspective from the consumers perspective its a positive that proves them with consumer protection which you won't get the same protection as a consumer with a bitcoin transaction.
This is where a L3, such as Federated Chaumian Ecash mints would come into play. Consumers that want charge-back ability could opt to use a FediMint, paying a fee for the privilege. The bare transaction fee would be even lower than Lightning, because FediMints could settle with eachother once a day only with 1 lightning network transaction. Customer fees would support the chargeback feature, but presumably these would be even lower than CC fees.
It might not be FediMints, it could be some other L3 solution that hasn't been thought of yet, but just an example.
At this point I would question the lightening networks ability to scale. Let's see what unfolds.
I agree, LN in its current form can't scale to every single individual. But it offers orders of magnitude more than L1. L3 will again improve scaling by orders of magnitude.
Each of these has a security tradeoff. If I were receiving 10 BTC for the sale of my software business, I want that on-chain transaction. If I am buying coffee from a shop, both me and the merchant are willing to trade a little less security and a little more trust in exchange for something that doesn't have enough value to warrant the security of L1, and the cost of that security exceeds the transactional value.
Do you really envision that in a another 5 years people will be buying their groceries and cups of coffee with Bitcoin (on the lightening network)? If that is what you believe can you describe why you think it will happen and how it will unfold?
5 years seems a bit short to me, but 20-30 years, yes. It may not be on the Lightning Network for low value transactions. It may be some sort of quasi bank relationship like FediMint. Even LN has far to much security for such low value transactions.
Not every person will be able to own a UTXO...and they don't really need to. In order to scale, there needs to be
some trust in the world. Do you trust your parents, your wife, children, your best friend, your neighbor? If there is a network of trust, there is no need for every single person to be able to transact trustlessly. Groups of trusted people need trustless transactions with other groups they don't know.
Also the biggest advantage that fiat currently has over anything else is that fiat in its physical form is 100% private. Unless you spend Monero you bought using cash or something you cannot get that same level of end to end privacy in crypto.
LN has good privacy
for the sender, however not as good for the recipient. FediMints have 100% privacy. There may be ways to improve privacy on LN as well.
Also physical cash is free and has no fee to use it (from the perspective of the consumer not the merchant)
Physical cash is great...in person. Most economic value is not transferred in person now.
And keep in mind the security risk of physical cash.
In all of the below cases, the government is immune from being sued for legal fees. All of the below cases, the people who got their money back, had to then paid it to their lawyers and court fees.
A 55-year-old Chinese American restaurateur from Georgia was pulled over for minor speeding on Interstate 10 in Alabama and detained for nearly two hours. He was carrying $75,000 raised from relatives to buy a Chinese restaurant in Lake Charles, La. He got back his money 10 months later but only after spending thousands of dollars on a lawyer and losing out on the restaurant deal.
A 40-year-old Hispanic carpenter from New Jersey was stopped on Interstate 95 in Virginia for having tinted windows. Police said he appeared nervous and consented to a search. They took $18,000 that he said was meant to buy a used car. He had to hire a lawyer to get back his money.
Mandrel Stuart, a 35-year-old African American owner of a small barbecue restaurant in Staunton, Va., was stunned when police took $17,550 from him during a stop in 2012 for a minor traffic infraction on Interstate 66 in Fairfax. He rejected a settlement with the government for half of his money and demanded a jury trial. He eventually got his money back but lost his business because he didn’t have the cash to pay his overhead.
Are you taking into account anywhere the initial fee to open a channel in the lightening network?
Yes taking the channel opening fee into account. The actual cost in the channel per transaction is usually 100-500ppm (parts per million).
0.01% - 0.05%
If you are using a Lightning Service Provider (LSP) that is basically a company that manages nodes and liquidity in exchange for a fee, the fee the merchant pays them is 0.5%, which gives the LSP a profit after opening/closing channels and managing liquidity within those channels.
