They shouldn't. If you want to make a wide page narrower you can always resize your browser. If I want to make a narrow page wider, there's no way for me to do that.
If you want to make a narrow page wider, you can open the Inspector and change the width.
The argument is the same, and they're both invalid. It takes way too much effort. I'm not resizing a window I use for everything just so I can fullscreen it when I switch to another tab and resize it again when I return.

The difference is that one is accessible to the average user. Outside of Developerland, most people don't even realize that the page they are viewing has a source which can be inspected or changed.
It takes way too much effort to resize a browser window? It's hardly comparable to going into the source of the page and messing around with values in there.
I'm pretty certain my mum, my daughter and pretty much everyone who's ever used a computer can do the former. I doubt that too many can do the latter.
