I am not talking about a public platform to download anything. I am only
talking about a Flattr-like system. Anybody publishing anything through the
Web adds one line of HTML to put a button visitors can click. The centralized
system would only receive one packet every time a citizen clicks the button:
it transmits who she is and who is the "content producer". It is technically
easy. Much easier than monitoring the Internet trying to identify who is
sharing what. Only a tiny part of the tax would be needed to maintain such a
system.
I think the biggest hurdle is protecting the non-libre assets.
If such a tax is introduced, non-commercial sharing *must* be legalized in
compensation! Nobody would have to "protect non-libre assets" because citizen
would have the right to share those assets. Watermarking data with
information identifying individual citizen should even be made illegal! For
privacy reasons (you can track who shares what with whom).
While people may steal music
They do not. They share music. Sharing is good. It should never be illegal.
