interesting to read this thread!
my first thought was also, as cracauer@, to think that i sort of gave up buying too much physical things (not that i buy lots of digital services)... but...
i spend money in food (making stuff out of non processed goods) and good drinks (mostly craft beer, wines (hey i'm french!!) and whisky (scotch, bourbon and some japanese and french/local, no rye)
and but so...
for more "lasting things": quite some books and LPs (i started buying physical music again some years ago, before i had a spell when i was unfortunately too broke to not "acquire it" by other more dubious means).
at some point in life i had up to 70 old film cameras, either in working order or for spare parts for the ones in working order (i used to be a professional photo-reporter). i thing i still have maybe 20, the rest i gave away of other enthusiasts during different movings.
i also have a gravel bike to exercise (not an expensive one but not a cheapo one either) and a small 125cc motorbike to go get bread (and not carry around 1+ ton of metal for a piece of bread, i live in the countryside and one needs a car for most things)
and a bit of it/electronics tinkering, i built an arcade cabinet with retropie and a lot of spare wood, a spare old cathodic tube screen (weights as much as a dead donkey) and lots of spare time during covid. currently gathering spare stuff to make a "cyberdeck"
i guess my first thought was dead wrong
