The internet is already creating far too many interdependencies that will have unforeseen consequences and create the risk of cascade failure. I strongly recommend to anyone that wants to tie something as important as government services to the internet that they listen to Dan Geer's recent-ish talk[1][2], and maybe reconsider the kind of future they are trying to create.
"Have you or a loved one ever experienced identity theft?"
"How long did it take to get things fixed?"
"Since your social security number never actually changed, what's to stop you from having new issues 5 or 10 years from now?"
"The cost of a pay-as-you-go phone can be less than the cost of "Identity theft protection"
If that doesn't work, let them opt out.
