What you're describing is actually a longstanding way of working, called a dock. Docks are fantastic when you don't have a proper desktop computer - drop your laptop in, and have all that nice desktop hardware.
But, besides having a singular environment, a dock isn't so useful when you have an actual desktop computer. Especially these days when laptops top out at half the RAM and cores as a baseline desktop.
When my laptop is functioning as a laptop, I still want connectivity. Both routine (SD/USB drives, headphones, HSM if I ever find a good Free one), and all the useful ports for ad-hoc situations (eg wired ethernet). Some of these do go away with time (eg RS-232), but prematurely deprecating still-popular ports and pretending that dongles are a decent solution for portable connectivity is ridiculous.
