>i guarantee almost no one will sign up. because we value life now like in no other period in human history

Plenty of people will sign up.

That won't stop whoever floated the idea from being fired and dragged through the mud. The majority doesn't really care about this sort of thing. A subset of society thinks life is still cheap, or at least no so ungodly expensive that it must be protected at all costs. However, the people who think life is infinity expensive are loud, vocal and their viewpoint is a simple absolute that is easy to defend so the rest of society caters to them.

Edit: And before anyone implies otherwise, I am specifically not passing a value judgement on either side.
