I'd build a compound in the woods and fund/train a group that would function sort of like a secret intelligence apparatus except instead of serving capital it would serve the revolution. Like a reverse cointelpro doing covert ops against fascists, pigs, capitalists and politicians.
I could easily see myself become apathetic because of an enormous wealth. It's hard to encapsulate $100MM so it's hard for me, a historic large adult child, to talk about how principaled I'd be and all the underground networks I'd fund. Frankly, I got into this because of how much I hate working. I learned about how unethical the whole gig is eventually, but it started with me being a lazy asshole who wouldn't have minded seeing their landlord, bank, and boss hanging upside down in central park.
I want to believe I wouldn't go around espousing the good word of capitalism, so I don't know how much of a traitor I would be. But if I'm talking that good leftist shit and a CIA agent sends me an email saying "knock it off" I'd shit myself and never espouse an opinion again. I could see myself taking my LED encrusted g*ming PC and my robot maid and riding off into the sunset.
