a budget gaming pc that requires minimal upkeep or research into picking parts or putting them together

if that isnt a good enough reason, counterpoint: maybe consoles just have no point then

Consoles are by far the best bang for your buck right now in terms of performance vs cost. A decent GPU alone today costs as much as a PS5/Series X. Unless you need a powerful desktop for other purposes, it's cheaper to buy a console and a decent laptop separately than it is to build a gaming PC.

You're not making a counterpoint, you're making THE point against exclusivity

So, if you're only buying a console to play that one or two games, they are objectively not a good choice to buy for you. Or if you have multiple consoles just to play all the exclusives, not for any actual feature of the device or cause it does something specific you want (or has accessories others don't, like VR), same thing. This promotes innovation.

If games weren't exclusive, you could just buy whatever console fits your use case the best, offers the best performance, or the cheapest for more casual gamers who don't care about performance who just want to play something every now and then. That's good for consumers.

So what you said isn't a counterpoint at all. It's just your reason for buying them I presume, actually proving they are bad for consumers especially in your case. If they had no exclusives, you'd just play whatever game you want on whatever platform you chose, losing nothing.
