It's weird seeing someone promote home gardening by selling grocery store products.

LLMs can be self hosted though. Using Claude to build a self hosting platform is a bit like telling people they should be vegan while you're eating a bacon sandwich.

In what way are those remotely similar?

Veganism is incompatible with bacon. You can self-host, and also pay for cloud services when they are better than what you can self-host.

If anything it's like suggesting making food instead of getting takeout while buying bread from the store, because it's better than what you can make at home.
