Are Bags Liability?

I was this close to buying one of those Osprey Backpacks online when the spirit of Rich Dad Poor Dad suddenly crossed my mind. Hey, I'm 28 already, should I focus more on future than these liabilities that can cripple my finances?

Yes, I am in the mountains, almost everyday, working my ass off, but I thought, well I can manage without one, because I have three bags now that I can use for work and play while I'm here.

Serious money saving activities must be done soon.
