I'm from other European country but similar things happen here. I disagree with you here. We should register ourselves as content creators and get our money back in other legal ways. We should demonstrate how much those taxes are stupid.
It is not "You Are All Pirates" tax - this tax allows me to legally make a copy of a work of art for my private use, even if I didn't pay for the original - it is enough that the work of art was already presented in the public [for example, song in a radio, movie in the TV or theatre, etc]. So I can legally have that stored on my HDD, if I choose so. For that, I have to pay the tax, and I am ok with that.
My main point was, that I personally agree with this model, and it is generally not that disadvantageous as the article and many comments here portraits it. Moreover, even the term "tax" is questionable in my opinion, because in this case you are getting rights for private copy of copyrighted content, it's not that you are paying for nothing specific [like in normal taxes].
