That's not very rational. will you have kids? Do you have loved ones? Do you have dreams/hopes? Do you have knowledge? Everyone has something to lose. Just because it's not tangible doesn't mean it's of no value.
I'm sure I'll eventually have more stuff when I have kids, but "owning nothing" now has just made things a lot easier.
Then, a few months ago, I was forced out of my home by a fire, taking only the bare essentials. Most of my stuff was undamaged, but due to the reconstruction work I couldn't get at it for a couple of months. That,as it happens, also sucked.
There's definitely something to be said for having stuff.
When I was a financial analyst I had tons of "stuff" and really it just caused me stress and worry. I liked the idea of having stuff instead of the "stuff itself". I think that's a PG quote. To each his own though.
