You do have valid points, but again it's all about cost of doing business. Fortunatrly majority of criminals are just people making money and not just crazy who want to watch world burn. So if their ROI is 1000% and they're okay with the risks they still gonna run their shady businesses even if cost of doing business will double or triple.
War on drugs has proven that it's impossible to fight this kind of activity no matter how much resources you throw at it. And running scams / botnets / extortion on internet is way less risky criminal activity than selling drugs.
> The US draws the right balance
Unfortunately it doesn't work like this in most of the world and US isn't about to invite remaining 95% of world population to join the party.
It's not that I support criminals, but majority of crime on internet (not counting actually selling drugs) is either scams, botnets or extortion. IMHO they all can only be solved by combination of educating people better and improving systems security overall.
Instead western government promise to solve crime with surveillance, draconian AML policies and censorship. After all it worked so well in authoritarian countries all around the world. /s
