@thewhitedragon69 well, we can see how attendance would not go up if cards were cheap either. MTGO proves that. Vintage is cheaper than Modern there and we have just a few players. I think it has a lot to do with what I said before (did I say it here or elsewhere?) of we having a bunch of formats and people not willing to dedicate to another one. So yeah, I don't think even full proxy saves us without other factors.
IF Wizard could launch gold border power or whatever, that were only allowed to a max of 10-15 in each deck, something like "official proxyes" to reduce price and still have "official cards", then maybe. But that won't happen.
