You can also avoid the permanency of owning things by renting/leasing/borrowing/returning for refund.

EDIT: I place zero value on the fact of ownership. That is, I derive no satisfaction from knowing that something (or someone) belongs to me. I am given to understand that this is rather unusual. Of course, I value having hassle-free access to things when I need them, and often the only way to ensure this is by owning them, but when there is a choice, I'd rather not, even if it costs a bit more. Unfortunately, the society around me is not set up for this, except for really expensive items, like a place to live or a means of transportation. I wonder if other places in the world are more access- rather than ownership-friendly.
