How is it complicated? Having to do these things made crime difficult. There's higher barrier to entry and cost to pay. It's more difficult to scale across borders. Not having to do them makes it easier.

The internet makes crime easier; should we ban it too? Before cars, you could only steal what you could carry--maybe we should abolish cars too. "Barrier to entry for crime" is not a useful metric, because it encompasses so many things.

Or do you want a police state?

You forget that internet makes police work easier too and there's processes for shutting down a dark market website for example

With e2ee though it's not like that
