Some douchebag would make the case that playing online poker is FREEEEEEEEEEEEEEDOMMMMMMMMMMMM!!!1!!1!!!
So is taking drugs, but it's 4/20 and still pot is criminal. Once you've established that, then you've established any vice can be outlawed at the drop of a hat.
It's not freedom to play poker anymore than its freedom to smoke pot. It's a privilege, and privileges are not free. Freedom is the right to live a life that does not disturb your neighbors without harassment. Once you get past that to incurring transactions, freedom becomes a muddied concept.
