15 transactions a day? I'm guessing that number is in the thousands, easily.

Manual input at restaurants alone should hit that threshold. As you correctly pointed out, reversing the transaction is very low friction, which is something I've not yet seen presented in any blockchain based solution.

Visa claims to handle 150 million transactions a day [0].

(150 * 10^6) * (1 - .999999999) =~ 0.15
