Someone who is not you could wonder:
Why you go through all these additional layers,
why you add all this additional complexity,
just to get to the Internet?
But you know very well why you are doing all this:
The Internet is not available through more straightforward means.
More speciffically, this particular internet isn't.
Whatever you can access "normally" is very different form this internet which you can see through all this CT stuff.
Even more interesting is the fact that when you change some settings of the CT card then you see a slightly (or sometimes not so slightly) different internet.
It seems that there is a lot of internets:
some similar to each other,
some different.
And this CT equipment allows you to see all this.
