Wrt projection we can create a finite point in space and just call it

That depends upon the space selected. :)

Say, okay, for our purposes, this is infinity, even though its not?

 It was about "fixed-point", with regards to fixed-point theorems,
it's a sort of usual thing then with regards to "point at infinity".
 It seemed not saying much, ....

It was about foundations, anyway thanks for confirming
you guys do not even have that excuse.
