I disagree with this. Theres nothing about this system which requires the world to be infinite. As an example, check out https://www.badnorth.com/ which uses wave function collapse to generate the islands.

The worlds are carefully tuned and aspects of them are controlled, but the algorithm is the same and I do think this creates worlds or at least aspects of gameplay with great interest.

An island does not a world make.

Sure you can generate small, believable structures with it. Like Townscaper demonstrates.
