mdd- thank for being courteous in your reply! However, I do not understand your response. The thousands of Poskim who had the responsibility of paskening throughout history had to deal with real life and real problems. Often, they adjusted their teshuvos to the circumstances (shaas hadchak, hefsed merubah,etc)Check any teshuvos and you will find a keen acceptance of circumstances.
In yeshiva (a very modern phenomenon, btw) one cound pasken in theory and disregard the consequences. You could not do this in real life.
