I once was broke and had to move across the country for a new job, and in the process get rid of years of accumulated stuff. I wish I could have afforded a storage place at the time, sure some of it was just junk / clutter, but much of that stuff was irreplaceable memorabilia for my first real career job that I worked at for over 10 years. I ended up using one of those junk disposal services - for a fee they take it all and decide what they can sell, donate, or take to the dump.
These days I could see the need if I had to move to an apartment - I am currently renting a small house and I set up a game room with dance game pads and a few home-arcade machines. An apartment likely couldn't handle that (it's one of the reasons I rented the house), but I wouldn't want to get rid of it all.
