I mean, none of that stuff in storage units is human communication, though. Nobody prints emails or text convos or insta photos. Nobody is mailing each other letters. So none of that stuff is in storage units, though plenty of it from previous generations might be.

I don't necessarily think all this digital stuff is worth saving, i just see how it could be that we are essentially erasing our modern historical record by putting 100℅ of it in private data centers with no permanent records.

And then you see how plenty of contemporary digital media from the last 30-40 years is actually already lost to time just in our short timeframe. I don't think acknowledging that this could be detrimental is necessarily an argument for trying to preserve all of it. We, as a society, went very rapidly from preserving a lot of it to preserving none of it. I don't see the harm in thinking about the implications of that.

Nobody actively preserved letters and menus and postcards and photos, they just persisted by nature of being physical. Digital records only persist with continuous effort to preserve them. So the record for future historians will be highly curated and likely much more limited.
