That was my worry before now, but I've been given a light that Hive Power serves much more than generating curation and staking APYs.

Your Hive Power is your governance power where you can support witnesses, vote for proposals and even operate your second layer tribes.

Holding an HBD savings will require Resource Credits which is a function of Hive Power.
