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).
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.
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.
