This also makes the whole prostitution business more shady than in fully liberalized models, like Germany.

It's basically saying "prostitution is bad and illegal but if you are offering it we won't punish you (wink)". Frankly it seems to me the worst of both worlds. The customer is automatically in a condemned state and can't redeem themselves. Kind of like how sanctions against Russia levied with no clear terms for removing them won't make them stop since you have basically made them your enemy with no honorable agreement possible.
