I do not see why governments would do that. Political decisions are not based on economic substance or common sense, but on sheer political interest. We - sadly - know a lot about that with the current Spanish government.
Why would a government make the public administration shrink? That would cost them millions of votes. They would lose any general election.
In Spain at least the administration is getting fatter and fatter, and all the ficticious "new jobs" are just friends getting unneeded positions at the public sector through connections. It's all nepotism and public spending. There's nothing substantial behind, no solid economic basis.
I think you're overthinking this. Putting something like a driving license onto a blockchain is not a big deal, and times change and evolve. We are heading into a technological revolution and you can ignore it if you want, but that's where we are heading.
The EU have GAIA-X which is a governance blockchain protocol that will likely have passports, licences, ID's, etc, stored on there. Cardano is doing similar work in Africa and other nations.
This is all "crypto" technology.
Take a look at this fairly recent article:
Gaia-X moveID project demos decentralized identity, blockchain for cars
MoveID is a mobility identity project launched a year ago by 19 companies and led by Bosch. Now it is readying for its first demo event at Europe's major auto fair, the IAA MOBILITY 2023, with six blockchain firms participating at the show.
The German government-backed initiative is under the umbrella of GAIA-X, the 350 EU member association for trusted data.
GAIA-X 4 moveID extensively uses
self sovereign identity (SSI), as does the mother project GAIA-X, to safeguard data privacy and enable autonomous transactions with vehicles. Blockchain is used as a 'vendor neutral infrastructure' to support transactions between cars, traffic infrastructure and other service providers.
The MoveID group also includes Airbus, Continental who are not participating in this event, as well as seven blockchain firms Chainstep, peaq, Datarella, 51nodes, Ocean Protocol / BigChainDB, Fetch.ai, and deltaDAO.

You can look into this stuff yourself. I'm invested in GAIA-X via Ocean Protocol as it uses their technology.
Here's a snapshot from the GAIA-X website:
This is just one small example. There's an entire industry that falls under the "crypto" umbrella that you don't seem to know anything about, and I mean that in the nicest way possible because the vast majority of the general public have no clue either.
