my main problem with the raspberry pi 4 8GB as a desktop PC is that first, the 8GB model is not exactly "cheap", and by the time you add all the extra stuff needed to make it usable (power supply, case, heatsink, fan, good sized of quality microsd card, etc) it costs well above a hundred bucks...
And for $100 I can go to ebay and get a used dell small form factor desktop with a core i5-something quad core cpu, 16GB RAM, 160GB Intel SSD which will run circles around it in performance as a real linux desktop.
The only thing the rpi has going for it is tiny size and its I/O pins which aren't so relevant if your application is "i want a desktop that can capably play youtube videos"
