I guess the American court system is a scam too because it's on the burden of the accuser to prove the claim!
If I produce a physical safe which I claim is unbreakable, but it appears to be made from paper, would you not want proof from me in advance that it is in fact, actually unbreakable
before you buy it, and then store your valuables in it?
What indication is there that VNL is made out of paper though? One can see with your own eyes that coins send and confirm almost instantly on the blockchain. It fulfills its main purpose for existing from the outset. It's like me going out and picking out a safe, closing it, locking it, and checking to see if the door opens when I pull it. If it doesn't open when I pull with all my strength or pop open immediately when I take a hammer to it, that is good enough proof it "works" as advertised.
Now whether there is a security hole in the software for the digital safe lock that is a wholly different issue. What product owner is going to say, "oh i'm sorry, my creation is not secure, you better not buy it". That is silly, for one thing they are inherently biased and will be protective of their own creation or they may just totally have no clue there is a problem and may believe after their own testing it is secure. Not every car maker that gets recalled rolls out automobiles knowing there are problems for instance. Hence that is why it is up to a neutral 3rd party to prove their claims otherwise and we have things like consumer reports or the FDA to regulate or warn about unscrupulous or mistaken claims.
Btw Bitcoin has exploits and bugs too, don't kid yourself, it doesn't mean the whole software is a fraud or insecure. Things can be fixed and risks mitigated. This is why there is a term in retail called breakage, shit happens and you have to take that into account as a cost expense of doing business. Unfortunately there are alot of Walter Whites around here expecting 99.999% perfection, it just doesn't exist anywhere.
