Its 2010, even the homeless have access to the internet.
No, no they don't. They'd have to have a computer - and not everyone has one, you know! There are still people with anolog TV's - they had to delay the termination of anolog signals because people "weren't prepared."
As for killing the second-hand sales - yes, and that is bad for the consumer. Switchgames has the option where you can donate a percent (determined by you) of your profit to publishers. But, honestly, if I'm selling the game, it is because I don't like it, and I don't want to reward the publisher for making crap. One person bought one game. Now I sell it to someone else. One person still has one game. I'm just the middle-man, like a store. That's how I view it.
Hey, do you think Steam will refund me my all or part of my money when I don't want the game anymore? According to them, I'm just buying the right to use the game - so, what if I don't want that right anymore, can I get a refund, huh?
EDIT: do you see car companies getting in a snit about used car sales? Do you see clothing companies throwing a fit about consignment shops? What about furniture companies, do they spew righteous indignation at someone selling their unwanted dining room table and chairs? Do book publishers get outraged when people donate their books to a library?
EDIT2: and for people with ISPs that charge by bandwidth, or have caps - doesn't having to connect to play eat into that budget?
