One big privacy issue is that there is no sane way to protect your contact details from being sold, regardless of what you do.

As soon as your cousin clicks "Yes, I would like to share the entire contents of my contacts with you" when they launch TikTok your name, phone number, email etc are all in the crowd.

And I buy this stuff. Every time I need customer service and I'm getting stonewalled I just go onto a marketplace, find an exec and buy their details for pennies and call them up on their cellphone. (this is usually successful, but can backfire badly -- CashApp terminated my account for this shenanigans)

Changing your number every year could mitigate as it would introduce entropy and stale data into the system. When done at scale, data lifetime would behave similar to the automatic deletion of messages on whatsapp. Somewhat mimicking an in person verbal conversation where only people's memories remember what was said and even their version gets changed every time memory recall takes place. Systems already exist in real life that protect privacy, it's just that we do a poor job of reproducing them with tech.

Changing your telephone number every year could be an artificial holiday like valentines day or halloween. It can be done if people deem it's important.

I already do this. It gives me an opportunity to trim the contact list to people I actually talk to regularly which I send the new number too. Also shows me my footprint online since I have to update the number. I only change it for places I actually use regularly or are important.
