>6TB for a family is not unreasonable and that's what?

Microsoft in particular has a 6TB for $100/year family plan, sharable with up to 5 other family members for a total of 6 persons each with 1TB. Google's plans can all also be shared with up to 5 other family members, though their bytes-per-dollar can't compete with that particular Microsoft family plan.

Basically: Local storage with personal management needs to be very easy, cheap, and carefree (which it isn't) to compete practically with cloud storage.

The only exception is if one's needs are niche and specific. I actually have a Synology NAS at home that I keep most of my data on, but that's because my data is mostly "bottle of rum" and "Linux ISO" in nature and thus not something I can throw on cloud storage in the first place.
