"Take Windows XP. Excuse me, but I have better things to do than "re-register" legal software every few weeks, for example."

Funny - so do all of us. Fortunately, Windows XP doesn't make you do anything of the kind. So that works out well :)

"Thanks to copyright and intellectual rights, software companies have more rights than just about any group."

This is simply untrue. None of the rights of intellectual property or copyright are specific to software. Thus, they have no more or less rights than anyone else dealing in intellectual property.

"and the rights of software companies due to copyright protection state outright that I am simply out the 50 - 70 dollars the game cost."

Actually, copyright isn't the issue. The issue is the license you agreed to when you opened the software. Currently those licenses are under contention in the court system, but they are still enforced often today. In other words, the copyright law only says (rightly) that a person/company who produces something owns it. All the rest of your problems come from the contract law that allows a binding license.

I fully support the laws on the books that allow the creator of a work to control the terms under which they want to share that work. There is no possible justification for saying that someone who creates something must give it away or sell it outright.
