Shit, man. If "financing things I don't like with my taxes" is the hill I'm going to die on, I'm going to set my sights on the insane military budget we use to turn far-away countries into toilets and parking lots.

Funding my fellow countrymen who want to squander their lives, so long as they're doing so peacefully and in the privacy of their own homes? Sign. me. up.

This argument has no foundation in logic. There is a subset of people who are fine with paying those taxes and do not care how the intermediary recipients of those funds spend them.

Even if you personally don't need or use the system today maybe it can be useful for you in the future.

Because all they care about is that people are given the opportunity? Your question is a complete non sequiter.

because of the multitude of positive effects it has on society that i live in. less depression, less poverty, less risky or criminal behavior, more economic activity, better educators, better medical care workers. this list can go on forever.
