It is very situational—I get that. But the fact of the matter is that most people have way too much stuff. This creates a huge amount of problems and headaches if you have to move.
Most of us here can probably agree that moving is a very good time to assess a lot of property. Much of which you probably were given/acquired at some time or another and really don't use.
I had a fairy minor (in the scheme of things) kitchen fire earlier this year. (Not my fault. Microwave burst into flames in the middle of the night.) Most of the contents are probably salvageable (or determined best replaced under replacement policy).
But I intend to be fairly discriminating as I move stuff back into the house. I had already started doing some sorting and donating/chucking bu this will accelerate it.
We're on the same page! I agree, and pine for the days before I acquired too many things. The contrast is observation: Most people I know, myself included, do not live that minimal life style. I know someone who does; he lives in a van and loves it; owns few physical belongings, and most are in storage. He's the exception; not the rule.
Personally, I have a molecular bio lab at home; I know (had to calculate for tax purposes) that it cost ~12000 USD including reagents, shipping costs etc. I have a nice 3D printer, loads of tools, a well-stocked electronics lab etc. All see regular use. A few pieces of oak furniture. I know that my personal hobbies are weird (Maybe not for this crowd?!), but many people have comparably equipment-bound ones.
Now, picture being married to someone with a comparable set of items (Furniture doesn't double of course), and kids...
