The mindset that you have to own the cards someday is where I'm lost ... why? Why not just proxy a vintage deck and then ... not buy the cards?
You got me there. I don't get that either, but it's the reality. Someone even mentioned this here (OP? Don't remember). The thing it that all of magic (Spike, Timmy, Jimmy, etc) are covered by other formats that are officially supported. This matters a lot. Why would anyone play Vintage competitively when it doesn't exist and Legacy does?
Why would anyone play it kitchen table style when Commander exists and can be way cheaper.
Sure, if people changed that mindset we'd get a bunch of vintage players, but they simply won't start playing. Also, it's a BIG problem finding calendar space to schedule events with all that's going on.
Creating a gauntlet of decks and lending it to people is the only way I got people to play and enjoy the format. What happened after that glorious event everyone played with my decks and loved the format? They never played it again because they spend their time building decks for formats they actually play.
So yeah, we should definitely play proxy. But it won't happen on a large scale and I also believe not having sanctioned big events like EW would be the nail in the coffin in the format.
