You can put a lot of stuff in a car. I have a fair amount of snowboarding stuff for example, but it does not actually take up all that much space. Camping is probably a better example, you can have an insane amount of camping stuff or a backpack full, but quality dominates quantity.

That's true and I could fit all my camping and climbing stuff in my car, but the picture I get from people who tout "all my stuff fits in my car" philosophy is that they live in a room with no furniture, a coffee mug and their laptop. Having less stuff for the sake of having less stuff doesn't seem to really serve a purposes. Keep what you need and want and ditch the rest. Not that complicated.

That's pretty dismissive of you to assume you know anything about me or my hobbies, actually. A lot of things such as my books and music were converted digitally, but I actually have an entire recording studio setup and my gardening supplies to move as well. If anything I spend a lot of my time avoiding online activities. You can learn to cram a lot into minimalism, not everyone is the hapless nerdotron you seem to think they are.
