"You see, I go and find the lion and I put a fence around myself. Then I define the area near me to be the outside."
A obvious exploit of jordan curve theorem; tee hee.
Oh, wait, I can't, because I don't actually own any.
Paul Graham's Stuff essay (http://www.paulgraham.com/stuff.html) makes the case for not worrying about possessions far better than this hilariously bad analogy.

BRK.A is a terrible liquidity example.
I've known for about a year that I was going to move November 2010, so that made me take a hard look at my possessions and what I had, and caused me to get rid of a lot. I've just moved with a suitcase and a few boxes, plus some boxes of books and camping stuff. Other than some electronics, I haven't taken any of my clothes out of the boxes, and I haven't needed them yet. I'm thinking about chucking them.
What ends us costing you your liberty is being stuff you can't afford with no plan to be able to buy it later. "because I am worth it" cost you your freedom
If we keep at hand only what we regularly need, and put the rest 'in storage', we'll probably be able to spend a lot more time doing the things we actually want to get done.
Take advantage of the division of labor and let someone else curate your stuff for you. Go do something interesting.
If you don't have either of those things, then I think you're right to covet them. :-)
Nothing wrong with having stuff...nothing wrong with wanting it.
I'll live frugally when I'm dead.
