[Avodah] lifnei iver/kanaus

[Akiva Blum]

Once you agree that either of these scenarios are acceptable, if not for the technicalities of where one is less of a certainty than the other, and we have the principle shelo yehei momono choviv migufo, than we must ask why a teacher cannot confiscate a pupil's property based on this principle, if he can indeed hit him.
Perhaps we can differentiate between where the rodeif is a killer, thus since he has forfeited his life, his property is undoubtedly worth less, and our case where the pupil has forfeited his right to a beating. Perhaps his property is more valuable to him. For a proof, see pesachim 25a: Rebbi Eliezer says why does the Torah say.. uvchol meodecha.. if there is someone whose money is more precious to him than his body..
