...the same is true for swapping two stickers on a corner.
If you alter the sequence of colours, you alter the finished pattern.
Therefore rendering the cube unsolvable.

Anyway, I think you're agreeing with the person you're responding to; they're suggesting it's more fun to peel and re-stick stickers precisely because that's a way to achieve states that even mechanical disassembly can't solve.
If you really want to make it physically impossible to solve and frustrating, swap two stickers between two cubes so they both have the wrong number of two colors, especially annoying with two colors on different faces of the same piece.
