Kiddushin expropriation

Hello. This is too broad a question to discuss here. I'll say a few things briefly. "Kol Dmekdesh" is an authority that is given to the greatest Rabbi of the generation, and not to every Rabbi. It makes no sense that every Rabbi would be able to confiscate a kiddushin and say that it was sanctified at his own discretion. There is no such authority today (certainly not the caricature called the "Chief Rabbinate"). This depends on the question of whether the confiscation is based on a condition (the former attach this to the statement "according to the law of Moses and Israel"), and then of course it is possible to condition it on whoever they want (although there is still a question as to who they really meant in this case), or whether it is a built-in halakhic mechanism (this is my opinion), and then it is clear that the halakhic does not condition it on the consent of every Rabbi. In any case, it is clear that an invalid divorce is not needed to confiscate a kiddushin (although I am familiar with this unreasonable argument). It is also not true that in all cases in the Talmud a invalid divorce was required. For example, the Temple Inc. confiscated its kiddushin. A condition in kiddushin is an excellent mechanism in my opinion (although the vast majority of poskim oppose it for some reason).
