I know it's natural for you guys, but you all have a very US/Euro-centric view of the format and proxies. Maybe in some places like Australia or Japan things are like that too, I have no idea. So maybe you think a format where players take control is OK or that proxies will solve stuff. But let me tell you how it works on the rest of the world.
No. One. Owns. Shit. A Volcanic Island is the same price as 1 month worth of rent, so Legacy is already broken. I play every thursday in a store that has to allow 15 proxies in Legacy or we don't have 8 people - not only because people don't have the cards, but because it's hard to walk around with a 2k deck when you could be robbed. We have monthly sanctioned Legacy, but a lot of people have to borrow cards and we've been discovering some fakes recently: so I have no idea if those 30+ players we get are actually OK.
Also, most people prefer to play Commander and spend their money there because sanctioned Vintage will never exist. Competitive players migrate to Legacy/Modern and casual player to Commander. The biggest problem is that Legacy and Commander are very good substitutes to everything Vintage has to offer, and they're cheaper to get into.
Turning to proxies is not something most people tend to accept because they know they'll never own those cards and that's a dealbreaker. In Legacy people use proxies because they're testing stuff and WILL get those cards later, one day. Vintage is impossible.
The world (not US, not Europe) only got Magic when 4th edition was released, so every single copy of anything before that was imported later somehow. So Vintage is non-existent and no one actually cares because it's impossible to gather even 3 people to play it. I'm talking about Brazil, the biggest and most developed country in South America, but that could be about Mexico or the whole Latin America too.
I know there are a bunch of people around (maybe here on TMD too) that think of us as underdeveloped apes that deserve nothing more than garbage and I'll tend to ignore idiots like those.
