The pools can't go against the law enforcement. They are companies obliged to pay tax to the government. When the gov ask them to censor a certain transaction, they will obey it.
Pools are central point of failures, I get it. But, Bitcoin is decentralized. If a pool is commanded to censor a transaction, then it is a matter of time until another pool will mine it. Even if 90% of the hash rate belongs to pro-censorship pools, Bitcoin will still be censorship resistant, because 1 out of the 10 mined blocks will contain all the previously ignored / censored transactions.
If they are commanded to reorg, then that's when the shit hits the fan. I speculate that there is no financial benefit from such an action, and it is suicidal for the business, but I can't argue it is impossible to ever happen. It'd just be the very ending of Bitcoin as a censorship resistant form of money.
Monero is an option and as I understand it, they can't go after the miners because the miners don't know what they are mining but they can go after the exchanges this time because they are also paying taxes and nearly all of them enforcing the KYC rules which kills the purpose of owning monero in the first place.
Which would be the point where people would start bypassing KYC and migrate to decentralized exchanges.
Needless to say that these are all bareless speculations of ours.
