I didn't say you'd have to buy a workplace PC with gaming capabilities, there is plenty of opportunities for a PC to be productive outside work and gaming (such as commenting on HN).
I can do all of those things on my phone (and I do!)
Not all things are quite possible on a phone or as comfortable as you could do them on a PC (I couldn't imagine coding on a phone).
And things aren't always as comfortable on PC as they are on a console. I would much rather the streamlined experience and guaranteed compatibility of a console for playing games, in the same way you would rather a PC for coding over a phone.
> since you pay lower platform fees
The platform fees (not required by the way) are roughly the cost of one game per year, if not cheaper. Gamepass being a very different discussion (and is available on PC too)
> This is in addition to the opportunity costs you incur of not buying a PC or having a lower powered PC as a PC can be used for other things (ie, office work, taxes, other productivity tasks).
I don't know about you but I don't want my work PC to be where I relax in the evenings, and many people don't want their employers software or information on their personal devices. I also live in a country where I don't have to fill in my own taxes, and almost all of my personal computing needs are met by my phone.
