To sam2,
on your second point, you seem to be saying that if a man wishes to violate the cherem by giving an unwanted get, it is possible for him to do so.
might be theoretically possible, but how?
he would need to find someone to be m’sader the get (probably can’t do it himself) and eidim and a sofer all willing to violate the cherem. Might also need shluchim, one or two shtarei harshaah.
and the delivery will not be as simple either, halachically, as you make it sound.
