to erode away at the name of things is to erode away the bedrock that holds this all up. it is to make the clear and the district muddled. there's no proposed new abstraction here, no new alternative: to hide the url would be to cloak the truth that makes the web so much better than all other computing: that this is an online space, where things have universal names[1], & that by using the name we can get to that thing.
I love your passion here, but I think this is pretty subjective. Like that model is mostly only useful for the document model of the web. So many things are apps now, where "URLs" only make nominal sense. Even in Electron apps where you can share URLs, it's basically just a bit of serialized state--you could use any format you wanted for this, but it's not at all universal: it's not like I could ever open a shared Spotify URL in VS Code.
But more broadly, I think we should maybe start giving up on the web (and by web, I mean what most people mean which is HTTP/HTML/JS). It is waaaaay too corporatized and saddled with legacy and politics. Let the ad people and the man get http(s).
if you want to do other things, don't see value in the expedition, so be it go else where, do other things. I continue to see this as a shared, mutual platform, one accessible to all, embued with ever more power, but yes, sometimes the entities not so far orable to us also make use of that power. this is not a defect to me.
