But seriously, does anyone understand why those companies don't just make all/most of their older games (in the PS4s case: PS,PS2,PSP) available digital from the start? I mean how hard can that be, wasn't there even that incident with the Vita where suddenly all PS and PSP games became available digitally? I think it would have been such a big plus if the complete PS,PS2 and PSP library or at least the best games from those systems would have been available on the PS4 at launch.

What's stopping them? Especially if the game is already available digitally on the PS3.

Because emulation for digital reissues like VC and PS1 games on PS3 is done on a game by game basis. It's not like PC where you can download an emulator and any game will work with it. The PS3 could play any PS1 game but the PS4 can't without an emulation solution. The PS4 also isn't BC with the PS3 so releasing PS1/PS2 games on PS4 without rewriting them like you suggest wouldnt work. 

PS3 runs PS1 discs just fine and I believe it's through software emulation.
