If your end goal is to get to cash it's quite difficult without doxxing yourself. For eg. imagine you do a ransomware hack, you have a BTC address with the BTC on it. Law enforcement as well as the company hacked both know the address. From that point they can follow where the money goes, it really doesn't matter how many different ways you elaborately transact.

You might try and run the BTC through a coin mixer however these attract attention and afaik are unreliable against an opponent like Chainalysis.

You can send the BTC to an exchange like Binance where you have not done KYC, however two issues with that. Firstly, law enforcement can contact the exchange and request halting the account. Secondly, without KYC you'll have very low daily limits and it will likely take a while before you can swap the BTC into something more private like XMR.

All your examples don't consider that we can trivially follow a wallet, get notifications when it does something and follow where the money goes. Yes law enforcement could absolutely knock on the doors of organisations that receive tainted BTC.

Speaking of global fracturing, partially true but I would still ask how do you intend to cash out? The only way that would work would be on a p2p website where you can directly sell to other users. This won't work if your somewhere off the map where there is not a lot of wealth. And somewhere where there is wealth you open yourself up to being caught if you have many large swaps.
