Not the person you responded to, but: I think that most people are savvy enough to know what a password manager is, and most people are not savvy enough to be interested in the work necessary to setup, personalize, and maintaining an offline password manager that functions well across multiple devices. That doesn't sound like a niche subset to me, but I could be way off.
Most of them can't and won't invest the time just to switch to 1Password. The average person isn't going to exceed that bar by a margin that even I, a software developer, wouldn't bother with.
When something is too technical for even an average developer to bother with (because it's unnecessary, not because it's hard), it is totally hopeless for the average user.
for a large amount of people, tech and non-tech alike, LastPass and 1Pass are really really good.
It's easy, unless you have actual data, what you have is an opinion.
I don't think your experience is representative. As I stated in my previous comment, I think the relative success of cloud-enabled password managers vs. more secure options like Keepass are a non-anecdotal form of support for this opinion. But I would be way off (which I also acknowledge).
It's already painful enough to use a cloud password manager; why would I burn hours more of time to maintain a worse experience?
> I keep a password database on the company network with all my work passwords and I have no need to keep a copy of those credentials on a bunch of my personal devices or cloud servers.
That doesn't work for mobile devices. Most people have a work mobile device.
> even if I wanted to use somebody else's servers to do that a properly encrypted file with a very strong password could be safely stored anywhere
This is literally how LastPass and 1Password handle it. If you lose your key, the file in the cloud becomes useless.

"A little extra work" that is beyond the skills of the vast majority of users.
> ...you gain a ton of utility and resiliency
As someone who used KeePass for more than 10 years until recently, I can honestly say that it was a massive reduction of utility and had no resiliency benefits.
