You can still have those at state level, or even lower, by grouping counties. The hill people from Appalachia deserve to be represented by someone local. The low lying coastal communities in the outer banks also deserve to have someone that understands them, rather than someone from NYC. The border towns in Texas are better represented by someone from there, rather than someone from Ohio. There is some value to local representation, it doesn't need to be all in. Romania for example has a hybrid system: it's "first past the post" first and foremost, so people get local representatives, but all the unused votes that would otherwise get wasted (both winning and losing ones) are then put together in a big national pool and then you have the second round of MPs appointed because of that pool. That way popular vote matches the percentages in the parliament, but you also have local representation.
