Your (maybe not 'yours' but let's run with it anyway) 'Perfectly legal' BDSM Dungeon is just one little piece of paper from being just as illegal as tax evasion. So, maybe we don't give people with paper power over our decisions. yes?
No. It would require the decision of officials of the City of New York whom I elected. Should they decide to make it illegal I would close. It would not require paper- there are a number of people who could issue a lawful order and have the premises closed. It's not about paper, it's about authority. Elected officials have it. You don't.
I like elected officials- they are much easier to deal with that the Party members back home, and if you don't like one- you always have a chance at a new one in a few years. Or can move somewhere they have an elected official you like. I also can't do that back home. Real decent country you've got yourself here.
Anything that I can't do are largely the result of my own limitations and not any obstacles they have put in my path. If you feel you're downtrodden that's terrible, but perhaps you could seek sympathy elsewhere because this Bitcoin thing would be really nice of it caught on.
