You need an open image otherwise it is grayed-out. 

O.K. Found it - but, as you said, it is greyed out.

File -> Open (some existing image)
or
File -> New for a blank canvas. (not much you can do straight away with a blank canvas)

According to my experience, these tools are pretty useless. Same with the G'MIC extract foreground filter.
I hardly ever use them.

Hopefully these tools will be improved in a future version of Gimp because from my experience the quick selection tool in Photoshop works really well.

For quick jobs i always use the lasso tool.
Sometimes a layermask works well, or a a channel as the base for a layermask.
For example with a blue sky, you can make use of the Hue and decompose the image.
In the end, you will get the best results with the paths tool and a layermask.

It is a matter of use and as you say you hardly ever use them

For a quick and very reasonable foreground extract g'mic is useful. This from a couple of years ago, using g'mic. The default settings have changed since then, from single layer to 2 layers (FG/BG) but the basics are the same.

Not everyone uses Photoshop.

Again, it depends on the image which tool to use. A path, then path-to-selection will produce a very clean cut-out but can be very time consuming and for a beginner a real PITA.

However I usually end up with a layer mask since this is a non-destructive form of editing.

Trust me, i have tried it many times and never got a good result. Setting the markers can take ages and then the filter still doesnt get it right.
Its also not very intuitive to use.
On top of that, it crashed a lot.

Its not about photoshop, its about the technology.
You could think from working with the rendering tools Gimp is offering, that it just doesnt work very well.
But it does. Gimp just needs a little bit more development for these tools.
And im sure it will happen, as soon as the developers are ready with the next generation of Gimp.

Im not saying use photoshop. Its hardly a good program in my opinion. Especially for the price.
Im saying there are working tools to select and extract, and Gimp will have them in time.
I mean the Scissor tool is already there, it just needs a better edge detection.
