From The UK Copyright service site:
According to copyright law, it's technically only completely legal to lend something if you're a library.
Now of course, resale is allowed because the aforementioned "consent of the owner" is implicit. Mainly because it would be silly and unworkable to force people to keep everything they bought, but also partly because that's just the way things are done.
This is a pointless side-track anyway. I'm not arguing whether lending is illegal. My point is that lending is morally no better than downloading, if you're going to play the "I like the original artists to get paid" card.
So? That first person buying the game will still have done so, regardless of whether you rent, borrow, buy second hand, download, or materialise from the ether.
What's VAT got to do with anything? That's not the cut that the manufacturers get.
But anyway, I get your point and no, they don't, and nobody seems to get up in arms about that, do they?
Also, why do you think new cars cost so much?
