Honest question: what would actually make you switch to a licensed shop

I mean this as a real question rather than a scolding. I hear a lot about how people should use the legal ones, and much less about what would actually change somebody habits. So I am asking the people who mostly do not: what is it? My guesses in order are price, distance, and habit, probably in that order, and maybe the fact that the place you have been going to for years already knows you. Whether those are the real reasons is not for me to say, which is why I am asking rather than telling. No lectures in the replies please, from either side. I am trying to understand it, not settle it.
