If you live in such a shitty country, the records would probably not be respected anyway. Also a blockchain still has to allow new inputs from a trusted source. And that source could still make up a fake sale and give your land to someone else.
(And no, priavate wallets wouldn't work to protect that transaction... because what if you lose your wallet?)
Why would the county not use their own system? What are you even talking about? You seem to simultaneously make arguments for and against blockchains in the same sentence.
Bro that's complete fantasy nonsense... Somebody has to also enforce the ownership. You ideologic internet stuff means jack shit if someone else has the gun.
Either you trust your city / county to keep track of land ownership (in whatever technical way they would like) and to enforce it or you don't. You can't magically get it both ways with "blockchain".
A central database would be just a list of all the land and who owns it.
Says who? Why would it not be a list of who owned/owns that land and when they owned it?
Would you rather walk up to a grumpy person with a shotgun and demand that they move out while brandishing a printout of an SQLite database recently recovered after the ransomware attack at the county administrative building? Or with a deed with their spouse’s signature on it?
Yes, the document from the county administration would be much better, than some "magic" contract from the internet that may or may not be enforced by the county.
Also if it's not in the code, it will get outdated quickly and nobody will ever look at it.
Separate docs are only really useful for main concepts that are not going to change that quickly.
To be fair a 30$ knife is enough... Definitely don't buy those fancy japanese knifes for 200$ or so.
