You won't be able to see a doctor when you're sick.

You won't be able to open a bank account to receive your salary.

You won't be able to buy train or plane tickets.

Well, they could change the laws to force people into slavery here, e. g. by forcing them to use US corporations ("if you do not have an app from Google store, you are excluded from society"). In that case they see age sniffing as ultimate tool of spying on everyone, so this is probably the real goal. What we all can see is that this has never been about children - they are just abused as the red hering here.
