Living in the US comes with certain advantages like some of the lowest consumer prices in the West including HW equipment being dirt cheap on the second hand market plus houses being big enough for space for such hobbies along with the biggest take home pays yielding some of the highest purchasing power in the West, a formula tough to replicate anywhere else.
At least compared to where I live now in Europe, such hobbies would definitely be unaffordable for me monetary and real-estate wise, which is also a monetary issue at the end of the day.
I was looking on an interesting blog about buying certain older ThinkPads or older multi-core server chips for $50 used for building a cheap home lab, and when I checked, super exited, on my local second hand market, such machines or chips were fetching north of €250 and that was before the chip shortage broke the market. That's just one anecdote, but you get the point.
