As a 20 year player, I don't see what the problem is with someone who owns P10 using proxies. These cards are worth $100's if not $1000's of dollars. What I've always done is bring my power in hard cases and used Collectors Edition copies in my deck as "proxies".
I would think that DCI might come around and allow this at some point in the future. You have to prove you actually own the cards but you obviously don't want your high value items shuffled by some idiot who bends, scratches or tears a $1500 Lotus. After its manhandled, its now worth $1000.I think that running proxies that Wizards themselves has actually printed is the solution that would satisfy most players.
