While I dream of a collection like this, I have nowhere near the funds to get anywhere close. Regarding priorities that need money, I too have things that need financing first. However buying the occasional farm and aiming for such a collection I believe is a positive thing. If nothing else, you're talking about items will both not lose value like fiat money and would be extremely important in the event of a collapse. If civilization didn't function any more, one of the most valuable bartering items would be a firearm and ammo along with it. It can be used to store wealth.
