Some will even require it for no actual reason at all.

Do I need to give my living address when I buy a sandwich? Then why would I need to when buying an online service?

Similarly, fast foods nearly all have these automated kiosques. They don’t need any info. So why do they require an email address when ordering to the table through the app, while in the restaurant?

They don’t need them. They just demand them because they can and everyone online is used to giving them without a second thought.

I can’t wait for personal data to become digital radioactive waste.

I just don't buy things online, and avoid anyone having my physical address that way.

Sadly, the ubiquity of terrible 2FA means at least some companies have my phone number, though.

> name, address, birthday and phone number

None of these things have historically been considered private information. There's zero reason that knowledge of any or all of this should be considered adequate or even relevant to proving identity.
