But when you make money from a website, it is a buisness. And if it is small money, it is a small buisness - where I found the buerocratic hurdles to be very small.

I mean sure, since I am a libertarian, I prefer there to be no hurdles and no taxes at all, but the majority of people think different. And you are not even a libertarian I suppose? So you just want a excemption from taxes/buerocracy for you? Or just for small things like donation? Yeah well, this is the case right now, but they need to somehow verify that it is indeed small. I found the current situation reasonable. A bit more effort with tax declaration, but not really much, having a small business.

"Additionally this can easily cause lots of trouble with the employment contract."

And this is a problem with your contract then, which you negotiated and nothing for which the state is responsible.
