Apparently not. :) Almost all countries have extensive rules limiting your ability to charge money for your labour, including but not limited to:
* Minimum wage laws
* Professional licensing laws
* Legal bans on prostitution
This is a widely misunderstood thing. Almost no country bans prostitution per se, not even most US states. That would be a gross violation of economic freedom. Instead they ban activities perceived as harmful: soliciting and pimping.
