I think people change their stance because they realized how inpractical PlayStation Now is, unless you have a stable connection you’re going to get visual glitches frame drops and outright disconnects, also even though you can run PlayStation Now on a laptop I wouldn't do it because my laptop just has so many…

PlayStation 2 emulators exist on PC if you happen to have a beefy computer and I believe you could just pop the disc in and run it on the emulator

If if my laptop can run most PS2 games at 20 to 25 frames per second but I'm reasonably sure a PlayStation 5 can run PlayStation 2 games at 30

If you don’t restart the story wont work properly
