It's kind of like a keyboard without LED lights for status, pop up tabs for the angle, and a recessed guide for the USB cable. Would it technically be cheaper without those things? Sure... but it also costs next to nothing to add them. Once a keyboard gets to $10 almost all of the cost is already put into "being the best keyboard for $10".

There are certainly cheaper, <$100 TCO, alternatives to the Pi or N100 PCs... but they are accordingly worse performing. One thing Pi is really good at is having well supported options on the ultra low end. The Pi Zero 2W for $15 - it's crap performance but cheap. The Pi Pico microcontroller starts at $4 if you don't need a full OS (or just need to augment an existing box with GPIO over USB). If you're building a PC out of a Pi it's just not a differentiated option vs an actual PC is all.
