I think I get where you're going with this. Instead of the DM going around and detailing an objective world where you have to know the DC of every lock beforehand, you just figure out the broad strokes of whether a lock is easy (anyone with the skill can get past) or hard (not everyone with the skill can get past it). The lock doesn't have an objective DC until you roll.As I see it, the DC is the arbitrary decision. Who decides what the DC of the lock is? That would be me. Is it a DC 14, 16 or 20-something? Erm. It's fancy, ok? Roll DEX.
It's almost like, instead of the lock having a DC and then you roll to see how well you pick it, the character has a static skill rating and the roll is to see if the lock is easy enough for that skill rating to be sufficient. If you go at it like that, then of course there's no way you could get past it unless your bonus improves!
Not my cup of tea, but I see the appeal.
