If we want to issue address space to folks for "private" use, it needs to be

But if we do this shouldn't we also take steps to prevent abuse
(hijacking etc) of those "private" blocks.
No, I don't think so. ULAs are for local use. We provide a mechanism
to ensure that they are extremely likely to be unique, but as long as
they are used locally, and confined locally both by routing and by
DNS, it actually doesn't matter operationally if someone else uses the
same prefix in their local area.
