Crypto Bubble 2.0 now absolutely is the primary reason for ongoing longer-term shortages (beyond immediate post-launch scalping issues), just as it was the last Bitcoin bubble time around pre-COVID, pre-scalping back when 1050Ti's soared to £200 / 1060's soared to over £300 without any prior scalping / stock supply issues. You're mixing up unrelated issues. Eg, webcams (and laptops in some areas) are short on stock due to a huge surge in working from home (even for old laptops that have a webcam built-in, the sensor quality is often poor enough that people want something better). For same reason there's also been an increase in demand for home printers / MFD's (can't use the office photocopier), ink & toner for same, etc. That has nothing to do with GPU's though as almost no-one needs a dGPU vs iGPU for just simple web / office work.
The elephant in the room is as Legacy-ZA said, the disproportionate lack of new generation GPU's visible in Steam HWSurvey relative to numbers being sold = a sizeable chunk of supply is being diverted for obvious 24/7 mining demand (where Steam won't be running). And since some scalpers are scalping for the miners, an increase in scalping due to increased demand from miners are not unrelated issues either. It's been 7 months now since the 3000 series launched and despite all this massive, massive demand and everything produced since then,
GTX 1060 & 1050Ti are still #1 & #2 whilst less than 3% of gamers own any 3000 series card (all 3000 models combined) should clue anyone into the obvious that a lot of what's being made isn't going to gamers regardless of whether it passes through scalpers first or not...
