You can do all of those things while also owning stuff. Owning stuff just makes it easier to relax. Instead of planning to relax... you just walk into a room with distractions available.
Having distractions readily available is benefitial to your mental health. Sometimes you have to not over-analyze your every action. Have an office which is empty, that's what I have, for when you need complete concentration. Stop making early-20s dreams your entire existence.
Right. But what about distractions that you never use but still end up having to maintain (which involves over-analyzing and mental costs)?
Minimalism is about making that same decision. It's about eliminating those things from your life that don't bring more fun to you than their maintenance costs. Stuff that is making it harder, not easier, for you to relax. What qualifies as minimalist living is an inherently personal decision. For some, everything can fit in a backpack. For others, even a mansion may be minimal.
Owning "only 100 things" isn't the definition of minimalism. Only an example. Like "delicious", "minimalism" is a subjective concept.
