If we actually got enough USB-C ports to make up for all the removed ports (like, 8 or so?) then I'd agree with you, and be willing to put up with the temporary pain of dongles for the sake of a glorious future where everything's USB-C. But we've ended up with the worst of both worlds: say I bring out my laptop for movie night and I want to plug in power, projector, surround sound, a DVD drive, and a mouse, that was easy 5-10 years ago and it's impossible now.
