I feel like the real problem is that much like QC people HE people selling it as "you can do some arbitrary computation [faster/completely securely]". Both QC and HE as currently theorized are extraordinarily limited in the kind of computations that can be performed. In the case of HE I cannot see how any of the schemes could be made to perform their quintessential example of an encrypted query applied to an encrypted database producing an encrypted result. Equivalently in QC land you have Grover's algorithm making DB queries magically faster. Old man shakes fist at clouds.
