Those are cheaper because they’re made with much higher tolerances. You can 3D print crude legos for nothing more than the cost of filament. But they’re not going to be any good.
General rule of manufacturing. Every time you decrease the tolerances by an order of magnitude, you increase the cost by an order of magnitude.
It’s greed. There are alternative “interlocking toy brick” manufacturers, like BlueBrixx, that are cheaper than Lego.
Bluebrixx are great! They’re also like 40% cheaper on average than Lego.

What you’re saying isn’t true, several other brands are as good and cost less.
