I'd scratch it up a bit first.

(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.

Ask your plasterer.
In general they are not keen on plastering overt artex, and latex paint
doesn't sound like something you can easily bond to.
Another layer of plasterboard is sometimes the safest option.

Depends, and I don't know it.
You might have to PVA it to get the plaster to stick, as for a reskim.
If the paint is water soluable (like artex), you might find that
as it absorbs moisture from the plaster, it comes away from the
ceiling (although you can normally get away with plastering over artex
itself).

IME plaster sticks well to any sealed surface as long as the first coat
is not too thick

No, and you have just discovered why latex paint should never be used on any
surface that you don't intend completely rebuilding a few years down the
line.

Choices:

1) try and get it off with heat gun = time consuming, stinks to high heavens
and makes a complete mess.

2) put up with the uneven, rough-as-a-bear's-arse texture until you move

3) re-plasterboard and skim

You /can/ skim over it as it is, but it doesn't stick well to plastic and
will crack up and fall off in sheets within a few years
