Why do you assume that level 1 characters and level 20 characters are looking through the same chest full of junk?
Why do you assume they don't?
Requiring the PCs to only find level appropriate challenges is silly. A city wall they want to climb doesn't grow 30 ft, becomes slippery and catches fire just because the PCs gain 20 levels over a few months.
And when you your reasoning it makes more sense that the difficulty is determined by what the PCs want to do and not what levels the PCs are.
