This has nothing to do with saying a Tzorech Godol wouldn’t push off this Issur of cooking by Ameira L’acum.
Your distinction between a tzorech gadol which occurs occasionally or only rarely makes no sense, and the entire 253:5 – R’ma, M”B, B”H, M”A, PM”G (including his quoting the D”M) is clear that even reheating is assur in some cases, and certainly full fledged bishul would be. I brought the M”B in 225 not as a raya, but as a possible explanation for why even the R’ma would asser by bishul.
You claim that the Debriciner in B’er Moshe is mattir amira l’akum l’tzorech gadol – please provide a source.
More importantly, provide a source for ANYONE who is mattir asking a nochri to cook, other than for a choleh.
You can look through all of the contemporary seforim on amira l’akum (they discuss the shailos in a more clear way) and you’ll find that none will be mattir, again, except for a choleh.
And as to your accusations that I and hello99 are either out to asser or to argue with you, I will point out that you negius is much stronger – you actually (it seems from your posts) were oiver on amira l’akum and bishul aku”m and are desperately trying to defend yourself.
I, on the other hand, and probably hello99 as well, came to the conclusion that it would be assur to ask a nochri to do melacha d’oraiso, even for the only available cholent, well before this topic ever came up in the coffee room.
