Because that's the only way Sony doesn't have a monopoly on what software you can run on your hardware.

PC gaming lets me shop from Steam, GOG, etc.

I can't do any of that on a closed system.

No it’s not.

Laws are.

Why ask that the fire doors in a building are unlocked when it’s on fire? Maybe they just shouldn’t ever be locked.

Ok. Even then you'd only be able to install specific PS5 software. Which no one can build without a license from Sony.
