You are correct. a minimum size is all you need. But that would vary according to sea conditions and wind.
The sea anchor is only used in extreme conditions and as an alternative to lying ahull or running with the sea or just carrying on with storm sails. I think lying ahull is the worst because you get rolled over.
I have sailed in a few yacht races in 60Kt winds and 10 m seas and have done the later. My son and I in different boats survived the bid storms in the Sydney to Hobart race with these tactics and at least finished the races.
Its all a mater of judgement at the time. Generally any option is better than getting in the life raft. Experience with storms in the UK and NZ have shown shown that stayed with there boat faired better unless they were actually sinking.

Subject: [world-cruising] sea anchor sizing........
I am puzzled about what I read regarding the chute size of a sea anchor
to wit:
I read that there are enormous strains put on the deck due to it's
deployment.
If that's the case why not use a sufficiently small one to reduce such
forces and to a degree not putting unacceptable backing down pressure on
the rudder ?
What's the possibility of rigging some rudder "helpers" relieving
pressure during such events ?
Is one presumed to have hove to while under chute deployment ?
As long as the boat heads up into the wind why is the minimum size that
will cause this not sufficient ?
It seems to me that even with some trials, that the size that would
satisfactorily meet the above criteria is unknown due to the myriad
differing variables from boat to boat, not to mention the conditions
under which such devices may be helpful.
Hence it intuitively seems to me that a balance between pressure on the
deck rigging from the chute would need to be balanced with the maximum
safe rudder pressure. But how all this is to be known in a given
instance, even with practice, would seem to a guess, which is
unsatisfactory to my mind.
Anyone ?
