Not really. Hoarding is no better or no worse than flipping IMO. Either way, you're buying more than your share, assuming that it's accepted that each person's share is 1 copy.
Personally, I don't care what people do, flip, hoard, or just buy one. Either way, they're pumping a lot of money into the game industry, which is a good thing for anyone who actually wants to play games. If I miss out on an LE because I wasn't aggressive enough, I'll either live with it or pay a secondary market premium on it if I want it badly enough. Realistically speaking, even with current secondary market markups, video games are one of the cheaper collector's hobbies that one can get into.
I agree with this. People can do whatever they want with the stuff they buy, but when people get all holier than thou about flipping, then theoretically, it's not different than buying one to keep sealed. You are taking one copy away from someone that wanted to open it, enjoy it, and play it. Is that as "bad"(I put that in quotes for a reason) as a flipper who buys 30? That's another debate for another time, but the basic premise at hand still remains the same.
There are a variety of ways you can break it down. I can tell someone that they don't need to keep one sealed, and they can respond by saying it's a hobby. I can respond to that by saying, you can still keep the same hobby, except just with opened copies, and they can respond to that by saying it's none of my business how they collect.
On the flip side, someone can tell a flipper they are taking copies away from someone else, and the flipper can respond and say they are hard up for money, they need cash, and this is a good way for them to make money in tough economic times. That it's capitalism, and this is what the country has embraced.
Point is, I don't think anyone is "above" anyone else.
