By that logic, nothing can ever be secure for any reason. We should all abandon the internet and go home.
From the string of your comments throughout this conversation, you seem to be making some weird, "I can't do it, so nobody can do it," false equivalency.
I don't know you from anybody, but I'm reasonably confident you're not more intelligent than all the highly incentivized people who have been, on the one hand, solving these problems against adversaries on the other hand who are every bit as incentivized to unsolve them.
None of the points I've made have been in any way groundbreaking or insightful. They're basic "I spent my free time for a year going down the bitcoin rabbit hole" stuff. You're throwing out incredibly basic objections as though they somehow mean the whole system is an unreliable fraud, but all it's really showing is that you haven't done even a cursory overview of the topic.
I'm really not trying to be rude here. People can understand code, even lots of it. People do understand it. They even understand the high-level cryptography these systems are built on. You might not, but that doesn't mean nobody does, much less that nobody can.
