For a more rough and ready, but quite entertaining, version of the DIY CNC (mill however) build there's the sage of Not An Engineer's build of a DIY CNC mill.

Why cast such negative aspersions on a stranger doing good work?

If you are smart and patient you can find good used machine tools for very cheap (relative to their new cost). I would guess that buying a new Honda Civic costs more than what this person has in their shop. And if you bother to watch the video, you see at the end that he takes what he makes home to a different shop, implying that this is a shared or borrowed set of machine tools. Buying a bunch of tools that will hold their value while producing more value is not a sign of being reckless with someone else’s money.

Would you make such judgements about every Honda owner for spending a five figure sum?

Know a guy who bought a 2 trailers loads of lathes and assorted machine tools for less than 10k in the Rust Belt. Was even remanufacturing diesel engines
