Have to say, I agree, at least WRT e-mail.  I see zero reason spam even 
exists in this day of cryptographic domain validation.  Indeed, just 
last night, I finally got DKIM working on my domain's emails, with the 
help of
https://www.stevejenkins.com/blog/2011/08/installing-opendkim-rpm-via-yum-with-postfix-or-sendmail-for-rhel-centos-fedora/ 
.
(Which, granted, was aimed at RH/CentOS/Fedora, but had essentials that 
did the job for Ubuntu -- especially appreciated the autoresponder DKIM 
validation addresses, though only the port25 one is working right.)

So if you check the headers of this e-mail, you'll see a DKIM signature 
from jots.org, my domain, and you *know* it legitimately came from me.  
There are other mechanisms that help, too, such as SPF.  I'd love to put 
a line in the sand -- say, 2/22/2022 (because why not?) -- and have that 
be when Google, Hotmail, etc., would cease accepting unsigned e-mail.

$.02,
