If I lose my phone or wallet I still have my passport and a mean of payment.
Now I foresee a future in which a cause of homelessness will be losing your phone.
First reasonable problem is simply losing it or it breaking. That is fun times if you don't have physical keys anymore. No car, no access to home, no way to contact the support...
And second is that I'm paranoid and I don't think it will be safe enough. Thus connecting absolutely everything to it and identity it provides just feels scary. I think I could possibly buy an apartment with a loan if there was ID connected to phone and it was cracked...
It won't. I believe we are actively setting up not only the biggest ever terrorist attack on civilised nations, which will dwarf 9/11, but potentially setting up a total and irrecoverable collapse. I find it increasingly hard not to think this is deliberate because I am unable to comprehend the colossal stupidity of our current trajectory viz "smartphones". It's like we want this to happen. Smartphone over-reliance is the single biggest national security threat I can see. We urgently need policy level thinking to shift things into a safer space.
Or just use any type of biometrics. You give your name (pointless, really) and agree to face-id. Face hash gets validated by gov server.
Facebook has solved this a decade ago. Big tech companies know 90% of population by name, face, all their kinks, activities, plans and desires - can the governments please catch up.
You may need to "walk" hundreds of km to reach one of those.
I do, too. Then I went to the US and wanted to grab a beer. Had to go back to the hotel to get my passport to prove I'm over 21. My EU driver's license wasn't good enough (it had to be from that state). I'm also old enough to start balding.
An iPad/tablet should do the job though.
