Gay marriage, pot legalization and crime-victim laws don't hurt anyone's profit (or, in case of crime-victim laws, the cost of opposing the law is higher than the cost of letting it pass) so there are no well-funded adversaries trying to kill these laws for profit.

This is the No True Scotsman fallacy. It's especially egregious given how well-funded opposition to gay marriage actually is. But even if we were in an alternate reality where the evangelical right (and the institutions that prey on them) weren't bankrolling enormous fights against gay marriage, the point you're trying to make would still be fallacious.

Most of the opponents of marijuana legalization are alcohol companies. Their profits are highly threatened indeed.
