Not everyone is annoyed with a locked closet, especially if it's just for a few months. Many people are fine with it, and it shouldn't be hard to find such a person.

Seems like one direct and simple way to go.

Most stuff that people are attached to and lug around is stuff that can be dispensed with. And it can be stored for free, short term, long term, or indefinitely, by turning the whole business over to the stores and warehouses and manufacturers. With no worries or responsibilities. It feels better letting go and going light.

You can just re-buy as and if needed.

There are plenty of charitable organizations and thrift stores that turn donations into good work, and it's nice to contribute and support and give. There are thrift stores that help hospices, cancer patients, animal rescue, victims of spousal abuse and domestic violence, medical clinics, young single moms, and others who need help.

Piling things up, collecting, and hoarding are bad habits.

A compromise approach is to keep just a very few things that are easy to store.

More and more I am appreciating the freedom and lightness that go with the approach of giving or contributing, and non-attachment.
