Don't take it personally. This question pops up regularly in the 20 years i have been aviating for a living, and will have done so long before that. It gets a bit tedious telling people why they can't just hire a plane and go barnstorming/ pleasure flying/ air taxi as a business.
Europe is over regulated by beaurocrats, and you have to follow the same rules as an airline. This is why the lighter end of GA is in such a poor state.
It is also annoying that people who hold professional licences don't know the rules, or where to find them.
