The first one is easily solved with one-time-use card numbers, which credit card companies have offered for well over a decade.

The second one is a dubious benefit if you're at all interested in stopping crime (eg money laundering is very easy if no party can block a transaction.)

Thats not to suggest there's no benefit to ETH, or even that crypto might be better than traditional money in some ways, but those two specific points are fairly easily argued.

Second issue is more political-ideological. Stopping crime is just an excuse. Current states will never allow a competing currency (against Fiat).
