My kids get some of the specialty sets, build them, then hours later they’re either taken apart or heavily modified.

The specialty sets can provide some interesting unique pieces too. My kids have a photographic memory of each of those special pieces and which set they came from. They’ll remember them and search until they find that exact piece.

> Sets become collectible, perishable, trends can form, secondary markets exists, etc. It's simply about the baseline, not the principle. Sorry.

I don’t know what this is supposed to mean, but you can completely ignore secondary markets and collector sets if you want.

There are more sets and pieces than ever. You don’t have to collect anything.
