I used to do the one bag thing while travelling until I had more disposable income and could afford taxi rides, baggage fees and all of that.

I used to own only things that I could move on my own and fit in a normal car, until I had more disposable income and hiring movers became a non-issue.

I still try to maintain non-attachment to material things but I now welcome enjoying material things in a functional way. For example, I own a ton of kitchen gadgets and that allows me to make interesting food, but I'm not married sentimentally to any particular gadget.

Things change, I guess.
