Can you download and resell a digital copy of a game you purchase?

If not, this doesn't seem to fix all of the issues it just feels like finger pointing at "evil copyright laws".

Yeah maybe we can change those to, but what about making it so if you pay for something you can do whatever you like with it.

Say if I buy a copy of a movie from Amazon I should be able to sell it to my friend who doesn't have an amazon account..
