I think it comes down to whether one considers oneself a "collector" or not.
For myself, I don't have the "collector" spring in my watch. I shoot. I drink good Scotch. I smoke pipes. But collecting guns or whisky or tobacco or pipes would make as much sense to me as collecting circular saws. (Of course I recognize that there is doubtless a vibrant and exciting community of circular saw collectors out there somewhere.)
So -- for me -- I'd simply never consider buying a tin of tobacco just to collect -- possess -- it. If it were something I sought or prized or had hunted for, if I were willing to spend ~$400 on a tin of tobacco, it would be to put that tobacco to the use for which God and the blender put it on the earth and in the tin. (Just like when -- not if -- I finally find that 1960 (birth year) bent bulldog in shell briar, ideally with the Cumberland stem, I am going to smoke the ever living daylights out of it.)
Now, it is an article of faith with me that I never tell another man how to spend his money -- especially once the kids are fed. So those who simply want to collect, have at it. But me, I'm smoking the stuff.
