No, but that doesn't mean you're right, even for your own use case, much less for anyone else's.
First, can you really say you're a minimalist if you're still using a USB mouse? I'd say that's a complete oxymoron.
More generally, it's not clear that littering the desktop with external hardware is better than using a simple dock. I just bought a 2017 rMB (my third, read on) and the single port is something you have to work with. I bought a $49 Satechi USB hub that's very compact and gives me HDMI video, 2x USB-A, and USB-C pass-through charging. It isn't burdensome and it wasn't expensive. Actually, what I really miss is MagSafe charging, but that's gone all across the Apple platform.
Keyboard. Well, yeah, that could be an issue for use. The originals (I owned two) were horrible, actually unusable. I've had this 2017 rMB for a week and have done a lot of typing on it. It isn't as nice as the keyboard on my 2015 rMBP but it's actually quite usable. Unlike the first gen keyboards, it's basically as fast, accurate and comfortable as any Apple laptop keyboard, at least in my opinion. YMMV but the improvement is significant. On a scale of 100, where 100 equals the 2015 and earlier MBP keyboard, the 2015/2016 rMB keyboard was a zero or lower. The 2017 version is probably 55-65, definitely usable for real typing, IMO.
Keyboard durability? I know the MacBook Pro forum is littered with reports of keyboard failures, and I agree, I wouldn't buy one today. But if you go back through the threads in this forum that doesn't seem to be anything like the sort of issue that it is with the Pro keyboards.
I was traveling on Friday and took the rMB. If you figure you want a little accessory bag for the charger and cable, the little hub is no extra weight or volume. The rMB weighs about half what my 13" 2015 rMBP weighs. It was really easy to travel with the MacBook. The display is great. The 2017 has a lot more speed and still runs cooler than the 2015s I had. They keyboard has not been an issue. Comparing it to a 10.5" iPad Pro, it's only slightly bigger and slightly heavier, and I can use Mac OS. And because I bought the MacBook for $950 during BB's flash sale, the MacBook is actually cheaper than an equivalent iPad Pro setup.
So, no, it's not a total bad design. Maybe for you, maybe for a lot of others, but for a lot of users it will work very well.
