This is a topic I obviously pay a lot of attention to. Wouldn't it be weirder if I came here with a different take? What do you expect?
I don't think I'm out on a limb suggesting that random small domains should not enable DNSSEC. There's basically zero upside to it for them. I think there's basically never a good argument to enable it, but at least large, heavily targeted sites have a colorable argument.
Actually I think it probably is suspicious to have the exact same opinion after studying something over a long period of time. My opinions are more likely to remain consistent, rather than growing more nuanced or sophisticated, if all I've done is trot out the same responses over a longer period of time.
I've struggled to think of an especially unexamined example because after all they tend to sit out of conscious recall, I think the best I can do is probably that my favourite comic book character is Miracleman's daughter, Winter Moran. That's a consistent belief I've held for decades, I haven't spent a great deal of time thinking about it, but it's not entirely satisfactory and probably there is some introduced nuance, particularly when I re-examined the contrast between what Winter says about the humans to her father and what her step-sister Mist later says about them to her (human) mother because I was writing an essay during lockdown.
It would make them more secure and less vulnerable to attacks. But lazy sysadmins and large providers are too scared to do anything, in no small part due to your ... incorrect arguments against it.
No it wouldn't? How exactly would it make them more secure? It makes availability drastically more precarious and defends against a rare, exotic attack none of them actually face and which in the main is conducted by state-level adversaries for whom DNSSEC is literally a key escrow system. People are not thinking this through.
Boy, how would cryptographically the ROOT of the internet make it more secure? Right here dude: https://easydns.com/blog/2015/08/06/for-dnssec/

Why? I can see this argument for large domains that might be using things like anycast and/or geography-specific replies. But for smaller domains?

It can reduce susceptibility to automated wormable attacks. Or to BGP-mediated attacks.
