On point three — again it could be that those exploiting ERTs might actually want secondary markets an so the envisaged design (though full of holes for sure) allows exploitation of them. It is not meant to be prescriptive. The same applies to the decay function. If it has a timestamp then I’d want others to choose their own appropriate decay according to their vote. They might for example want a really high decay, or even hard stop on tokens issued before x date, to participate in a given vote. Leaving it open means it gets used in multiple ways and becomes a very flexible tool. Of course it might be so flexible that no one uses it because it loses specific utility.
