I don't know why so many people are under the impression that they do thinness for thinness sake. They do thinness for lightness sake.
The lighter your laptop (or tablet, or phone), the more you'll choose to not leave it behind but rather to just lug it around with you, and so the more places you'll have it and the more it'll be there to aid your productivity in random situations. [Also, for phones and tablets specifically, the longer you'll be willing to hold it up to your face to stare at it before putting it away due to the "gorilla arm" feeling.]
Sometimes I actually carry my MacBook around in my backpack when I'm just downtown for a meet-up and have no plans to do any work. I get it out for the same reasons you might pull out an external Bluetooth keyboard for a smartphone—e.g., if you want to type a long response to an email, or need to type a snippet of something that's awful to type on a phone keyboard, like code. Except that this Bluetooth keyboard happens to have its own computer attached to it.
(I don't use it at home, though; at home, I use a Hackintosh with a real keyboard. Which happens to be an Apple Magic Keyboard 2 with the exact same butterfly key-mech in it that the MacBook and rMBP have. But Magic Keyboard 2s aren't getting gummed up left and right, because the butterfly key-mech itself actually works fine when it's given adequate travel height. It makes a huge difference; you wouldn't even think it's the same key-mech!)

I didn't know how true this was until upgrading from an old Lenovo T400 to a newer Lenovo Carbon X1. I'll regularly carry the X1 a few blocks to a library, park, or coffee shop. The X1 and my work laptop - a Dell Latitude - are about as thick and heavy as the T400 alone, so it's not even a question that I take both to a location when working remotely. Now I need a bag with 2 laptop slots.

Conversely, the Samsung Tab A has enough magnets in the back to stick to a fridge - this remarkably makes it feel heavier than the X1, especially when working on magnetic tables and surfaces. The Tab A causes the "gorilla arm" feeling almost immediately, making it basically worthless to me. To add insult to this injury, when it's stuck to my fridge, the screen refuses to turn on when rotated to landscape. So it can't effectively play full-screen Youtube while stuck to the fridge, negating the last use case I found for it. I think this is due to a magnetic screen-off sensor that all Android devices seem to have on the back, but don't know why this would only turn off landscape and not portrait.
I'm jealous sometimes of my girlfriend's Samsung ultrabook for this same reason. I think it's Samsung's answer to the LG Gram and wow, it's light.
If you want a really light machine, don't you have to ditch the aluminum? My 2017 MacBook Pro gets heavy, esp once you add the charger. I take it everywhere.
They're both similar metrics, and both just vanity now.
There are lower bounds of acceptability and luxury that were hit years ago, with much more important things to work on now like battery life and connectivity. Nobody cares about shaving another few millimeters or grams off the design if it means a frustrating experience overall.
The Magic Keyboard actually doesn't use the same butterfly key mechanism: it's a scissor switch, albeit one that attempts to emulate some of the feel of the butterfly key keyboards (but with more travel).
