I recommend politics. Local politics can get their presence in your neighborhood to chill, set examples for other municipalities, and lead to broader office (if done well). Legal, community driven, and fairly direct. Does require talking to your neighbors, sometimes in public, which is a substantial downside.

Failing politics, I think your next best bet is probably attempting to do some hacking/espionage work. LLMs make this more scalable than it used to be, and they seem pretty happy to hack big companies. Costs a lot of money, will enrich other tech bros with high probability, definitely illegal, and it’s pretty hard to do this hard enough to crush the business (tho if you can siphon enough money out???). But you won’t have to talk to a neighbor or speak in public, so that’s nice.
