I too love the web, but throughout my career the idea of web-first/web-only has been DOA. There is some level of perceived prestige from having an app.
I've told this story countless times but on multiple occasions I've written cross-platform apps using web technology. Throughout the development process, I have urged or even begged the stakeholders to try out the web-based version on their phone. It's almost identical. You just see the browser chrome in the web version. And yet it's not until I provide native builds that some people will even bother to look at.
I provide web interfaces as part of the package but I could probably skip that and no one would bat an eye (I won't though, it's practically free to do that alongside the native apps and I prefer it).
There are a handful of things you can only do, or only do well, in an app so I do understand that argument. Also, I find some PWA-advocates to clearly not be living in reality: "You can do X in a PWA" - only if you hate yourself and enjoy silly limitations that clients do not and will not understand or care about ("Just make it work, an app can do this!").
