Someone clearly has to pay to keep to SEPA infrastructure going, be it the banks crosssubsizing from profit on lending or taxes funding organisations in EU level.
Crypto fees are just much more straightforward. You pay a small amount to use the network and there are no strings attached, no hidden subsidy. In theory at least that is because most networks are still funded by inflationary payouts. But no one is forcing you to hold anything more than you need to pay for fees in the crypto currency at any moment in time.
Just like with most things crypto has been widely oversold and 99% of coins are basically scammy penny stocks. No one disputes this. But as someone who has moved internationally quite a bit I would LOVE for all my ETFs and bank accounts to live on an open Blockchain so I don't have to worry about migrating everything when I move to a new country. Even if I don't fully custody them, moving USDC through Ethereum or Solana is just 100x better than any international wire transfer. Stocks are basically stuck in whatever country you bought them in, I don't even want to know how difficult it would be to move my depot from one country to another. You'd have to sell everything.

Not sure what you mean. It's not significantly more difficult that it would be (and maybe easier) to be constantly transferring blockchain assets to local currencies/equities etc. ACATS makes the process pretty straightforward and handles most common financial instruments like stocks, cash, bonds, ETF's, and more. Then you're done, your entire portfolio transferred in a few days. Just choose a good brokerage firm in the first place: ACATS participation should be a prime criteria if you might move country at any point, ever.
Similarly, USDC/Ehtereum/Solana only seem superior to a wire transfer until you have to use them in a local economy. Then converting them to something compatible with the local economy isn't significantly better.
If you're imagining a future where local economies accept these things directly then I think that future is, at best, possible but mostly theoretical at this point. Crypto is not a major threat to sovereign-dictated monetary policy at the moment, and I suspect that the second it appears it might be then there will be rapid action to cut off that potential.
I don't see a way that crypto can bootstrap fast enough around such things when a government can, pretty much overnight, make every business own and retail cashier who accepts a crypto payment into a criminal if they so choose. Gray and black markets might still prosper, but it would make any vision of mainstream use, much less institutional use for things like inter-country investment portfolio transfers completely impossible.
