Well, I do enjoy the layers of protection implemented here. It sounds like you wouldn't?
The record from the land registry includes things like wayrights for third parties, known ground contaminations, utilities/water/power lines etc. -- all very relevant to me as a potential buyer. I did enjoy the notaries explanations of various aspects, which went beyond reading the contract out loud and making sure we verbally understood what we were going to sign. The process also forces both parties to have written copies of everything prior to the final meeting, which provides another chance to let it sink in and potentially reconsider -- which in our case, we did. Also, they're really trained to verify IDs, not like a random clerk in some liquor store.
I understand one can experience it as "bureaucracy" and "annoyance" in their individual case, but then I wonder how much such people consider the bigger picture and what the benefit of all of it really is, for their own and for societies sake, and what kind of shitshow it would turn into if we got rid of all the "bureaucracy" -- such as described in the very blogpost here.
Even if I (wrongly?) assume I am always on top of things and I will not get ripped off ever, only so-called stupid people will, I really don't need more angry people who fell for scams or made quick decisions that they regret or whose identity got 'stolen' around me/on public streets/in bars. If it was for me, we could add even more such layers of protection, which you seem to see only as "(unnecessary) bureaucracy"?
