It deincentivizes abuse not unlike how SSL originally worked before it became a farming operation.

I remember as late as 2004 trying to scrounge up copies of our business license to fax or mail into our registrar.

Today the SSL cert has lost it's identity aspect and is just a sign of secure communication, not trusted.

And those policies made it impossible for personal and hobbyist sites to use secure communications, while doing very little to actually prevent abuse. (Most of the apparent "success" of these policies was simply because the motivations for abuse were lower at the time.)

Ease of SSL certs provides significantly better protection from threats between you and legitimate sites than potential illigitimate sites.

Fraudulent SSL certs weren't a thing because the barrier to entry way so high and the rewards for spoofing a site were low since e-commerce was insignificant.
