It's a conflict of interest in that it's in the bars' (financial) interest to let people through.
It's not in the bars' financial interest to create a minimum drinking age via regulatory capture just so they can hire bouncers, or accept bribes or sell fake IDs or whatever. That's analogous to the insinuation I picked up upthread (if I read that comment correctly). Expecting industries to self-regulate until they show themselves incapable of doing so is pretty standard.
