Taxes may be levied unfairly and they may provide facilities that individuals don't use. However, they are for collective benefit, public ownership and with nominal charge for use, at most. In the case of recordable media levies, the law enriches a private industry to the detriment of the public, distorts a market to the detriment of the public and doesn't exempt us from further fees. Specifically, after you've bought one blank CDROM, you're not exempted from one album sale.
