It's easier to disallow something that used to be (and may formally be) permitted than to add an entirely new requirement. Some kinds of reform to tradition are harder than others. Judaism and Halakah were not designed with our modern notions of sexism in mind. It would be a very worthy thing to change them to the extent that we can, but to the extent that religion is a non-governmental matter, that's not very easy, and getting consensus among the various communities of Israel would be very difficult for any change.

why bother with a vindictive cruel man like this? respect his wish to die- his wife will be a happy widow- she does not need a get- but she GETS all his money- . Why should she have given up alimonies in the first place- they are his children too- . This guy is a mental case- the wife should get power of attorney of all his money and property- and put him in a mental institution.

The Rabbis of the Talmud were already aware of problem of the power divide. In Ketuboth they suggest a concept called Hafkaat Kedushin, similar to an annulment, for just such a case when a husband has clearly abandoned his wife but refuses to give a get. It may not equalize the power between man and wife, but it gives the Rabbis the power to intervene - not only by twisting the man's arm, but by freeing the woman from the husband's manipulations once and for all. It may not be easy to find consensus within the various Jewish communities, but in the long run it is "easier" and more effective to fight the issue on a more systematic level and not one awful husband at a time.
