As somebody that was required to pay an extra of 700€ before to be allowed to read my thesis, in concept of "insurance" (that, surprise, surprise, the university never provided but still billed) I can tell you that this is not very realistic.

It just adds a new member in the table sucking researchers dry. Who will pay for this insurance?, the grants earned by this scientific? Then this is less money that goes to the researcher one year later. Those that hire researchers will need to either increase the funds or to allow some free hours in the contract so the researcher can double jobs working in McDonalds.

The principle of moral hazard suggests that paying for insurance makes people more likely to use it.
