What is the accuracy in this ? Aka if I run the experiment 10 times how many differences will i get? I don’t have a physical sense on what would be a good number.

You would get a lot of differences, but the errors would cancel each other out with enough depth of coverage.

This technology's baseline accuracy is around 95% per base, so 10x reads of every segment in the sample would give >99% accuracy for each base after aligning the reads with each other.

If it's an US-based lab, aren't they subject to CLIA with all its retention requirements?

For $7.5k+ you get a guaranteed privacy (as other comments suggest, other properties may vary, but at least the data never leaves your home).

Oxford Nanopore unfortunately has a high error rate (3-5%) compared to other sequencing technologies. And the errors are non-random

This assumes random errors, which IIRC isn't the case for Oxford Nanopore.
