Is NAT can provide some kind of protection?

I hope the engineers in the organization will just tell their marketing folk
that it's not possible to hand out just one IPv6 address.  "Our hardware
doesn't support it."

I think there's still room for ISPs to charge $10/month for a static prefix,
though.  And that's technically possible.

How do you know - have you asked 100% of the service providers out
there and they've said unanimously that they're only going to supply a
single IPv6 address?
