It really doesn't. 51% (more properly, 34%) attacks show that it doesn't.

If it were done properly, i.e. with verifiable append only logs run by a
known set of entities, then it would. It would also be many orders of
magnitude cheaper. Stupidly cheap, in fact, instead of eye-wateringly

I do wish people would stop perpetuating this canard.
