How many of them without any corporate backing have the same requirements as a payment processor?

> There is of course always a cost for a transaction one way or another, but it still stands that you pay 0 for the transaction itself.

Again that's not the full picture, just take the Uber example. If they had made rides free thanks to VC money, would you have said that they solved the taxi problem and made them free so it's a much better alternative?

The problem with this kind of accounting is that you can't tell whether it's just running at a loss or whether the technology is actually better than the rest. Visa and others could make transactions free if they didn't care about losses.

As a user, I'm also not interested in, say, getting a new credit card transacting in $crypto that will either not work anymore in a while once they've run out of money or start billing me fees when it's clear it's become unsustainable for them to have free transactions.
