By the logic that PSP needed to use generic cables that weren't sold together (ignoring that the hw and fw itself supported it) then now that some smartphones are sold without charger then it must mean they have infinite battery right?
It can`t be any more obvious that Switch is a handheld first and with some tweaks to make it easier to play on the tv or share multiplayer.
Yet the hardware and firmware DO support TV-play, and that's the difference.
But you even notice how rediculus your argumentation becomes?
By that logic, you, as a living being, do not exist, because the sperm and the ovum you originated from werent put together right from the start.
As long as the manufaturer intends the product to have feature xy, it doesnt matter if the components are sold seperately or together.
Just question yourself... what would the psp be, if sony would have decided to put out a bundle with both psp + component cable together.
And right next to it, there would be the psp alone. But both use the cable for tv-play, whether it is included or not.
