Well once upon a time a console was a small fraction of the cost of a PC and the experience was put game in, turn console on, play game. Sure a console had a fraction of the computing power of a contemporary desktop but typically they had hardware specifically for graphics and sound and games were usually coded very efficiently for the specific hardware often directly in assembly.

That hasn't been the case for a good long while now. Consoles and their games receive updates just like PCs do. Yes the purchase price of a PC and its associated hardware is probably does still cost more than a console...until a few months of paying for those subscriptions go by. Console hardware is now very closely related to PC hardware. So the value proposition is for the price of a low-end gaming PC you get a lower-middle class gaming PC with a 90% less useful operating system, recurring costs and worsened versions of games.

Meanwhile Valve says "Yeah we made using a normal gaming PC on the living room TV work pretty well a WHILE ago. Also, you know the Nintendo Switch? Well we've built a full fat gaming laptop into a similar form factor of portable device. It's an x86 PC, it runs PC games natively. It runs Linux, you can get to a desktop, hook it up to a keyboard and mouse and you can do spreadsheets and run CAD on it for all we care." And it's been such a big success that several competing products have been hastily pushed out that run off-the-shelf Windows and none of them are as good.
