> I was worried about the societal implications of being unable to prove land ownership but it seems that may be avoided.
You know, it's not like people would come and steal your land overnight because you can't provide proof of ownership.
People can come and cut down trees, use the land for their cattle, raise crops or just start building something. If you don't challenge it and they get away with it for a while, they could even gain use of the land legally.
Happens far more often than you would think in developing countries.
After the tsunami that hit Thailand and wiped out many fishing villages on the Pacific coast, the people were evacuated but as soon as they returned, they found the local mafia occupying the land, and as they had no need and there was no land registry, they were forced to rebuy their land.
Squatters, boundary disputes and rent defaults happen all the time.
Plus having most of your net worth locked up in something no sane person would consider buying off you because you can't prove you own it is ... suboptimal
