If you pitch it as “authority of a driver's license combined with the convenience and security of a chip-based credit card”, it may not be hard to get people on board. It might help to bundle it with benefits such as more automated direct tax filing.

Our country’s post office operates a Datová schránka (“Digital Mailbox”) system where you can basically send email-like messages to people, businesses and institutions that carry the authority of registered mail but delivered in a minute and 10x cheaper. This is optional for individuals and mandatory for businesses, and you need to authenticate with your ID card online or at post offices (which also accept driver's licenses and passports) to access it (though you can get email/SMS notifications of new mail). The cost is there to limit spam, and to send a message, you need to know the recipient’s address (public for companies, private for individuals unless they choose to publish it). Most people don't use it but businessmen love the speed and reduction in paperwork. Because right-wing people tend to adore business efficiency and this makes contracts fast and secure, this might help the US ID adoption too.
