I hate needing a phone number to function in life.

Having a phone number means unsolicited phone calls.

Having a phone number means unsolicited text messages, often from political organizations asking for money...so they can continue to spam people. And it's not illegal to spam people if it's for political reasons.

But too many systems demand you have one. Employee management software, government agencies, etc. all demand you have one. So you gotta have one.

I'd rather everyone just email me instead. At least, on my desktop, I can setup inbox filters to get rid of crap I don't want without ever needing to see it.
