I share that sensibility, but it makes more sense in spaces that have already acheived a "wild" equilibrium.

In many cases, existing crafted landscapes can't handle the acidity/moisture-trapping/etc of decaying leaves. So you're really advocating for people to give up on expensive, considered, laborious projects that exist for functional or aesthetic reasons. Even if there are alternatives that are comparably functional or beautiful, what's there is there already and a lazy wilding doesn't necessarily lead to one of those agreeable alternatives.

It's a bigger ask than your phrasing suggests.
