I think a lot of these issues are political (whether farmer lobbies or kosher keepers), but yes you're not getting 100% the same availability as if you could import everything but it's mostly fine. And this is in a small, very densely populated & arid country.

If Israel can get 90% of the way there with mostly minor annoyances like what you listed than most countries can probably get even higher (with the drawbacks of higher prices & the rare lack of availability of a non-crucial commodity).

Also keep in mind that the low cost of imports is partially because externalities like pollution are not being accounted for.
