More like $30 for a coffee machine and $250 for a dishwasher. Then $150+ each for external monitors.
Maybe this is what you wete refering to, but I could only find Bill Gates guessing grocery item prices:
It just depends on if you want nice stuff or really basic stuff. The nice stuff costs a lot more than the prices you quoted, just like a nice midrange car like a Camry costs a lot more than a basic, bottom-of-the-line car (Yaris?).
Considering the audience of this site, I would assume most here would buy higher-end stuff, and not the cheapest things available.
It's kinda like my fancy tea infuser cup: I have a nice glass mug with a laser-cut stainless-steel infuser for loose tea. It was $30 at a fancy store (could probably get it cheaper on Amazon), but it's a one-time purchase. With high-end loose tea, it makes great tea, but the problem is cleaning: cleaning out the infuser (by hand) is a lot more work than just dumping a tea bag in the trash and putting a regular mug in the dishwasher. But the results certainly are a lot better than a $0.20 tea bag.
To highlight the absurdity of this estimate: $2000 USD should be enough to pay for an entire work-from-home setup with a high quality office chair, an ergonomic keyboard, and a whiteboard in addition to what I have mentioned above (assuming that work provides your computer).
Although it’s not 4K, given the fact that it ships with a color calibration report I think calling it “some gaming monitor” is a bit silly.
As someone who’s a bit of a picture quality fanatic (I preferred color accurate panel displays “before it was cool”, my television is a 4K HDR10 OLED, etc.) I think it’s quite ridiculous that you’d classify your suggestions as anything other than luxuriously decadent for most programming work.
Edited to remove a claim that I haven't seen 4k monitors, since I just realized the big displays we can get must be 4k. We can only have one of those though and they're not as fancy as you're claiming.
