Eyeing the price graph of that 3060, it might be "commonplace" among the population that built a gaming PC in the last couple months, or went all-out in the past ~1.5 years (availability not taken into account).
Most people I know don't have a desktop in the first place, and on average I wouldn't guess that desktop users build a new one more often than once every ~4 years. And that's among people who build their own; if you buy pre-built, you have to spend a lot extra to get those top of the line specs.
It's possible to now go out and buy this on a whim if you have a tech job or equivalent salary, though.
