I don't seem to be able to agree - is it confusing for us in reality to be able to enter any publicly accessibly building like shops? I also don't think one can realistically expect every building to be enterable, but notably more.
It's a question of gameplay then, however. You could argue as well: How meaningful are more enterable buildings if you cannot do much more beyond the simple fact of exploring? A compromise then comes in: Add world interactivity. Put shops, food stands or other interesting things or street stories / mini-interactions and then you have something meaningful.
Costs time to implement, however.
Another compromise: Strong modding akin to the Fallout / Skyrim game series. Then the community can do it. Of course, developing a strong modding kit that sufficiently allows you to do the same magic (or at least some of the core magic) like of the aforementioned games costs resources too. But consider it like an investment: With a solid modding kit, you unlock the vast modding and enhancement potential of the whole community collectively and many talented / experienced modders.
It's not meant sarcastic, but they can do all the work oneself couldn't finish in time, or didn't decide to do for design choices. Or in other words, the players can then influence the game in the direction they want further, to their personal liking. This is always what I saw as a huge benefit of the okay-ish Fallout or Skyrim games. The strong modding kit. With it, the games became much more gun. Here, we already have a very good game in terms of world building and story telling and with good modding, it could become even better.
