It’s optional to buy new gpus and games that require them.
It’s optional not to buy a car but it certainly limits your access to things.
Yeah if you need your GPU to go to the shops, or to work, or to visit your family, that would certainly suck.

Putting aside the fact that i was in no way claiming you could do all the exact same things with a car as you could with a GPU.

There are in fact jobs that require a dedicated gpu.

No, but you likened lacking a GPU to lacking a care in terms of stuff you would thereby be unable to do. I was making the comparison explicit.

I certainly did not say that nobody needs a GPU for their work.

Fair enough
