That’s how it works in the US too. We don’t record documents with the county recorder to make them official, we do so to provide notice to third parties who might purchase the land.
Recorded deed will more or less universally contain a legal description of the land. This does, in fact, defined the illegal outline of the parcel.
A survey is little more than marching out into the field and putting at the location where you believe the boundaries to be based on your review of the legal description.
Of course that’s not the end of the discussion as to boundaries for reasons like adverse possession or busted titles but on his own a surveyor is going to tell you basically nothing.
Generally, those markers are placed by the person who did the previous survey. They’re not really official designations of anything. However, if you look around, you will find things called survey monuments. Sometimes they’re embedded in the sidewalk, or the middle of the road. Out in the boonies sometimes there’s a little concrete pedestal that has the marker on it. Anytime you look at a recorded deed you will see a legal description of the land and generally that description will start from one of those monuments.
Software providers generally lack a duty to their clients to create and sell secure software. Further, generally, when you get hacked, there is only an interrupted causal chain between the software and your loss. Interrupting that chain is the intervening superseding cause of a criminal third-party. Finally, no states allow punitive damages, absent gross negligence in a software context.
Country recorder has a list of judgements against people and entities found to be in breach of contract. This is what exists but probably not what you were thinking of.
> People believing they are entitled to dictate what other people do with their property
Yes, I believe that’s called “society” and while we are all very disappointed about your personal liberties I’m afraid some compromises had to be made to allow people other than you to have property rights too.
