How would such verification work at planetary scale?

Most platforms for the last decade have used phone numbers for real-human detection. Facebook is well known to quickly lock new signups' accounts until they give a phone number. Obviously that can be gamed by some people in some places, but all countries on earth have mobile phones now and purchase of a SIM card often requires showing ID to authorities.

		how would a phone number proof uniqueness though? I can buy multiple SIM cards even with showing ID

Who cares about planetary scale? Back when your networking reach was largely limited by the size of your area code, local BBSes had user verification and were incredibly popular.

		Nextdoor is the only social network I have used that confirms your real-life location, and it's not any better than the planetary scale sites. BBSes were better due to how users self-selected into them. Small geographic clusters don't inherently promote quality.
