Lego is pure IP (both from LEGO itself, and then e.g. Disney or whoever is behind the theme of a given set). If you get sets designed in China and made at the same factories that make Lego bricks, they're like 1/3 the cost. If you get sets designed in not-China but obviously ripped off ("Star World" sets that are 1:1 copies of Star Wars legos), also in the same factories, it's like 1/10 the cost.
The manufacturing isn't easy, sure, but it's more or less a solved problem and not at all reflected in the cost.
So when GP says priced like Lego, they just mean that - priced based on something completely different from the cost of materials, manufacturing, etc.
