It's not sufficient, of course, but it's still the best we can do now, not only for mere safety but also for innovation, interoperability. In such an open world there is little room to purposefully sell crap to sell after fixes for instance, and that's very bad for some business but very good for the society and for nature, much reducing waste. After a certain amount of evolution even swapping component became harder, because anything is really transparent enough you still have margins, but with higher risks than now and more important much bigger reputation damage, which hurt much in such society (remember the Internet Manifesto for reference). Beside that the guarantee does not exists in nature, but the likeliness of an event have a really big impact on our life.
