I have to regardless of a storage unit or in a closet in my house. That closet in my home and that shelf in my garage isn't free either.
So then it's just a question of owning anything at all or nothing, because it all has a life long recurring fee for the privilege of continuing to own it. And yes, my family finds value in decorating for holidays as a part of celebrating, remembering, and keeping traditions alive.
Sometimes people don't just want to live in the same IKEA box 365 days a year.
Your standard also doesn't make much sense. Garages can vary from barely being able to fit a compact car to having like a four car garage with a workspace area. You're saying that for both instances that's just perfectly the right amount of storage space for those people? The person with the small garage just isn't supposed to have any of the same hobbies as the person with the giant garage?
I guess I could just get rid of all these tools though. Every time I need something fixed I'll just not do it myself and just pay others instead of just doing things myself. I guess I could also just give up on a ton of hobbies we have. We can just throw away our family traditions that have been passed down for over a hundred years. I'm not wealthy enough to live in a house with enough storage space with the other constraints about where I'd like to live, so I guess I just don't get to have these hobbies and traditions and heirlooms.
Or I can just spend like $500/yr and still manage to keep all these hobbies and traditions and heirlooms.
I don't have space issues because I do get rid of stuff and I don't buy much stuff but I still have a bunch of stuff I would throw away or sell before renting a storage.
