I agree with the underlying conclusion but there is one thing you said but did not properly reason about:

> On the other hand, van life and tiny houses are logistically prohibitive to having children.

This is just not true. Only here in the wealthy west people think they need a big house to have children. In the rest of the world you will see whole families living in one tiny room together.

Also there is a lot of valid reasons not to put children into this world without being part of some lifestyle romance.
