Growing up, actual peak existence was visiting Grandma's house and playing with my mom's old toys. The seemingly unlimited, completely novel hoard from another time. My son feels similarly about visiting my parents' house and playing with my old toys. This may or may not be sustainable but it seems like it is well on its way with four generations involved- from where I stand, keeping a good pile of consumerism around to pay it forward in 20 years doesn't seem out of proportion with the joy I've received. It's definitely a culture thing- nobody in my family tree seems to move much, and has decent taste in throwing out the actual trash and keeping stuff stored nicely over the long time gaps, then not being fussy about the next generation being pretty hard on stuff (within reason, as appropriate for their age)
