Space is unique in consistently attracting comments like GP's. Literally no other endeavor, no matter how boring or silly, attracts these. Has been so since before the Internet, even.
Even pointing out that this is just private company doing private stuff - so no government money to accuse of being misallocated, which was the only thing that gave those evergreen comments some legitimacy - won't help. I guess it's just inertia now.
At least this is talking about homelessness and not feeding people; the latter was getting too easy to push back on by pointing out just how much space contributed to farming and food security.
