I agree! Recently I have been wondering if there is any reason why for example Android devices with a camera don't implement the USB video class specification, except for the reason that nobody cared enough.
Even low end android phones take selfie video of way better quality than any built in laptop Web cam I've had experience with. Also unless you spend 200eu for the top end cams you won't get near that quality. At 200eu you can actually get a pretty decent mobile phone like oneplus nord which also has a decebt camera.
