Birth Certificate - What it is

[walter]

That they are clearly taking liability for the PERSON is worth noting.

Pauper's were the church's responsibility. That's why the church kept the register.
I think it was Benjamin Franklin whom said when asked about what they did about the poor in America. (before FRN;s)
His response was that there were none.
Everyone had work and there was no unemployment.

If you think about the BC the main reason you need one is because you don't have enough funds to live in today's world.
You need it to get a job to make money.
You need it for health insurance because you can't afford the Dr.
You need it for baby bonus money.
You need it for unemployment money.
You need it old age pension because you are broke.
etc.
The poor are liabilities to whom ever jurisdiction they sit in.
