Eh.. no, I think this is reductive.
In addition to being closed PCs, consoles are also an OS and collection of services that make playing games easier and make the process of configuring the device easy.
They also often come with unique hardware (3DS, Wii U, Switch, Vita) that offer dedicated features that don't make sense on PCs.
Most importantly, consoles are standardized PCs. It's not that they're closed, it's that if a game says it works on the Switch, and you have a Switch, that's it. That's all you need to know. PCs offer a lot more complication because there are multiple hardware variations and because the OS isn't specially designed to provide a lot of dedicated frameworks and interfaces to make running games and taking advantage of the hardware easy.
I don't think any of those benefits would go away if 3rd-parties were allowed to make compatible games without asking permission.
It would be a lot harder to loss-lead the hardware, sure. And it would maybe have some implications for quality-control if anyone could start selling unplayable games at Walmart. I'm sympathetic to those arguments.
But I think it's reductive to say that the only reason anyone would ever buy a console is because it's a closed market.
