As a Swiss I second that. I will vote for it, but I expect it to get less than 10% of yes's. It's 10 years too early. Switzerland is progressive in many ways but it is also conservative in many ways - this sort of risky experiment is the kind of thing that will almost certainly not pass for now.
It's true that it will certainly not pass. But the main objective, as for any referendum, it's to put the debate on the public place and just that it's a unique privilege.
