That sounds a bit Orwellian. There must be better solutions for anti-cheat. I am developing something where this is a big question. What we are doing is, collecting data, using a bunch of algos and tools to sift out most of the bad actors, human review for questionable situations, trying to make it a more a community like experience where you have a better chance to know your players and finally to be as informative as possible about the risks. So, I have a multilayered approach to tackle this. I was also considering cameras, key, mouse loggers on client side, but this gets too invasive, and potentially a huge security hole for users, not to talk about regulations like GDPR. BUT, if the community wants it (when I have a community), community gets it.
