Right Sandy, I take all of your points and agree with most of them but I guess there's a couple of points here -
Firstly I wouldn't advise the purchase of thigh waders (nothing the matter with using them if they are already in your inventory) but breathable chesties are the way forward.
Now, wearing them does not mean that their existence is so that I can stand up to my 'thruppeny bits' in aqua, au contraire.
Handy for sitting on a wet and muddy bank and watching the river
for fiording the river and fishing the other bank
for added security when returning to the bank after fishing a 'waded' run (lots of sections come to mind that increase in depth righ at the bank).
I also remember having to drop into the river to tail a Salmon (high Summer with the usual bankside vegetation and absolutely nowhere to beach it) water was up to my jewellery.
I could go on but I know you get my drift.
The post was 'to wade or not to wade' (for fishing purposes) so I agree with your sentiments on this .
don't take it personaly Sandy
