If your ideas remove my freedom to have branded goods, exclusively branded goods, then they interfere with the way I have chosen to live. Luckily I am in a majority so there is no danger.
Law and rights are social constructs designed to make life better than anarchy. As you say, the majority can decide that killing someone is OK and in fact do so every day to 1000s of unborn people. If you disagree with this, the way to deal with it is to persuade people life would be better if the law changed.
Since your idea doesn't improve life, there is no real point in trying to decide if we need laws or rights or any other implementation details. Its a waste of time.
Do all of those unborn people get to have a chance to "cast" their vote? Kinda hard to do when you're dead, huh? I am attempting to persuade you. Your IP laws conflict with my personal property, and hence interfere with the way I have chosen to live. Get your chocolate out of my peanut butter please.
Posit a solution to the IP vs. PP issue and maybe we can move on to more important matters.
The issue is solved Rights are social constructs designed to make life better than anarchy. That includes property rights - we create the rights and we create their limits. In this case, the right is limited by the greater right of intellectual property.
What you are proposing is to remove the intellectual property rights and expand the property rights. Since that would reduce my rights (I own trademarks and I actively like branded goods like cars and drinks), I'll say "No thanks." But my mind is open - I can accept that I may be a loser and society can be a winner if you have a better idea. If you can show that society will be better off without intellectual property rights, of course I will agree with your concept.
EDIT: off topic but yes I do try to persuade people that abortion and euthanasia laws are a muddled mess. Its strange that you can kill an unborn healthy child but you go to jail if you help a sick person to die.
