From a US-centric perspective, those things are true. But the rest of the industrialized world has largely solved access to medical care (even if they are still working on timeliness in some respects). Child care has been solved in parts of the world through a combo of subsidy and parental leave - you can look at parts of Canada and Northern Europe for some models. Housing is tricky - areas are expensive because they're either on the coasts or near major economic hubs. In a post-scarcity economy, there will still be upward pressure on the former, but the latter eases quite a bit. We'll see it sooner than this, though, as tech starts to go more and more remote, and production processes become more and more automated. Not tomorrow, but optimistically, within my childrens' lifetimes.

I agree with both of these. Both of these problems have some political solutions, though. They're not technical impossibilities.
Why involve the insurance companies at all? They're just a drain on the US healthcare system.
If you cut out the insurance companies, changed the rules about price gouging in the pharmaceutical industry and engaged in preventative medicine (such as offering support to those who wanted to lose weight), the US could easily afford publicly funded healthcare. Other countries with fewer resources have managed it just fine. Even if you have to raise taxes to do it, you could do so and still leave people with more money in their pocket compared to when they were paying out insurance premiums.
