Except this isnt really about liberty, it is the self/exploitation of glamour girls for the pleasure of a few pervs. And just like consuming drugs is illegal for moral reasons, the exploitation of these girls should be illegal.
You’re argument that the individual should decide what is morally good for oneself kinda trips, when we already have many ‘moral’ based laws on theft, rape and murder and they are not decided by the individual. They are in essence ‘morals’ to protect socitey.
Secondly, if for example, liberty really did exist, then why for example is it illegal to walk around in the nude in those same countries? You can be arrested, fined and perhaps even jailed. Where then does the ‘individual liberty’ you are tooting around so eagerly, come in?
