OK, so no one uses CRT monitors any more, so why would you want one of these?
Firstly, there is the pretty obvious thing that it only takes a moment to screw the stand of a LCD monitor to the thing with a couple of self-tapping screws, if you do want to use it as a stand for one.
But me, I use one of these from Brooklyn, as a laptop stand in the kitchen. It works brilliantly, whether it is showing a recipe as I am cooking, being used as a webcam monitor to keep an eye on the kids in the garden or just to watch catch-up TV or whatever. It hardly uses any worktop space (and who has enough worktop space in the kitchen?), swings out of the way in a second. Built like the proverbial, so can take anything from a 17" monster downward. Having the screen at eye level makes it easy to read without stooping and it can be swung and extended so that I can still read it whether I am cooking or preparing.
I also have one of these fixed to my work-bench. For much the same reason - there is never enough room, to hand, on a work bench and one of these arms, with its 32kg carrying capacity can hold so much - whether it be test equipment, tools or even that laptop again.
I know, it isn't going to be everyone's cup of tea!
