Checked it again, this sentence is still there:

"I mean this in the sense of "activities that also satisfy the above criteria", but suggestions don't have to satisfy ALL of the criteria. Here are some of the first ideas that come to mind when I try to answer the question myself:"

Most of those criteria are extremely subjective - For instance, many people would say that programming needs expensive equipment, a specific location, and is nerdy instead of badass.

Similarly, all of the subjects above can fit all the criteria when you know what you're doing, how to practice them and how to use them.
