First two flaws are imagined, (OMG it's not absolutely identical to the current system that's failing!!!) and we're not in the Wright flyer stage still, that was 2009, more like a DH 89 Dragon Rapide or something. Development has continued, we're just about to go onto 10th major version of reference client.
Third so called flaw is a user idiocy problem. User idiocy is not a design problem until involuntary euthanasia is legal.
