With you it's all about yes or no. The decision seems to be between allowing people to build a 20 story bonfire in a suburb or banning candles from the entire nation.
Someone has to decide yes or no, and I'm trying to put myself in the shoes of that someone. Also, I'm not going for the hyperbolous here.
You used to live in Texas, right? Hot and dry. Recipe for fires to all too easily burn out of control. Say your neighbour Cletus is a complete imbecile, and your other neighbour Becky Sue is upstanding and very sensible. Turns out that they both like to cook over an open camp fire in the back yard. They do it right, they may both never have an issue. Do it even slightly wrong, and maybe your house with whoever happens to be inside it, burns down.
The hot and dry place that I live in has laws that would prohibit any such fires on days with conditions deemed to be at too high a risk level. The law would ignore any competence that Becky Sue might have over Cletus and deprive everyone equally. Since it's a law that denies indiscriminately, and is ruling on risk rather than absolutes, I'd imagine it would be a law that goes against the libertarian ethos. Does it? And if so, what is a feasible real world alternative? At some point someone has to step beyond theorising and get down to brass tacks.
I'm listening to a cover of Radiohead's creep right now and thinking you're already living in that reality. Honestly, the "remixes" are out of control with copyright. That you can "sample" basically the whole song is ridiculous. I'd like to see copyright protection be more like patent protection. You can't just take someone's song, make a few tweaks, call it a remix, and release it as your own. That's crap and everyone knows it. It doesn't stand in movies, I have no idea why it stands in music.
An out and out cover of a song will provide the original writer with mechanical royalties. The sampling thing is of course completely different, and kind of all over the place. I do have friends that have sued producers of songs that used samples of their music, and made lots of money though.
You obviously separate intellectual property from other types of property? Also, given the 20 year generational theory, shouldn't we be well and truly past the point where anyone can make and sell their own product branded as Coca Cola? I asked you in the SOPA thread back in the day about your view on trademarks, but didn't end up with a response.
