Should it be necessary to have a PS2, PS3 AND PS4 hooked up all at once to play?

How else can money be made from "remakes"

Huh?

Remove backwards compatibility, remix content, and rerelease.  Look at what has been done with Halo and also a number of PS2 titles on the PS3.  There is HD remakes.

I didn't get how his answer linked into the question.

I saw it as, "Why have backwards compatibility, when you can sell remakes?"  In short, backwards compatibility undermines reselling old content.
