If you watch the Tom Scott video, the owner goes into the maintenance and why he was selling the property (IIRC).

Yeah, I've been watching; his video's implementation supposedly just requires an annual lubrication of the bearings taking about an hour. That said, the guy's trying to sell (for health reasons not related to the house) at the time, so I'd want... independent confirmation.

Perhaps every 10 years you have to hoist the entire house up with a crane and redo the seals.

The video of the central core looks like that's unnecessary; it does appear to be built to be pretty easily maintained.

Eh, lifting houses with jacks is a well-established process. As long as there's crawl-space access to the understructure of the house, you could slide some jacks in there, jack it up six inches or a foot, do whatever maintenance you need, and then jack it back down.
