What is so bad about keeping all your games and peripherals, just to upgrade the box (PS4 to PS4.5)?

My problem is that the PS4 has nowhere near even touched on the idea of being worth it's value. Out of my 34 games for it only 10 of them are not cross-generation titles or remake/port.

So it hasn't been worth it so far and they are already gonna make my system obsolete when i could have just waited.
