So in the end I guess the 243 guys are getting by but wishing they had more because they recognise the need, just need to work harder to obtain it or use it an an excuse...

Maybe.....other than in cases like mine, where I originally had (and still have) a .308 and then decided of my own free will to buy a .243.
One reason for which, that I forgot to mention earlier, is that I guide clients deer stalking for muntjac and roe on a fairly frequent basis. A number of those clients may not have their own rifle and indeed some may not have shot a rifle before at all. Not all of these "newbies" are kids, by the way, and bear in mind that the UK doesn't have the same culture around firearms that you do in the US. So the closest many may have got to a real firearm is seeing "a short chamber Boxer Henry point 45 caliber miracle" in Zulu!
In circumstances like these the low recoil and low noise of the .243 are very attractive. Combine the above with the types of deer these clients are likely to see and (hopefully) get a shot at, and the .243 is - perish the thought - optimal. The last thing you want when guiding someone is to worry whether they will flinch when pulling the trigger. You want them to enjoy using the rifle, enjoy the zeroing, and enjoy the whole subsequent deer stalking experience. Stick them behind a .270 for their first ever shot and some might not come back again!
Others who have their own rifles may elect not to bring them, and instead opt for the "estate rifle" clause and borrow mine. Again, it would be the .243 I'd put them behind, and no-one has ever objected to using the .243.
So I sort of look upon the .243 as the "lowest common denominator" of rifles for deer in the Southern Britain - and that's not meant as a criticism by the way.
Of course once those newbies have been out a few times I tell them to "man up" and use the .308
To close, I have the choice of two identical Blasers in the cabinet, one in 243 and one in 308. Unless I'm going to Scotland or abroad, I always pick the .243.
