"The problem are the people"?!
As in Bitcoin itself is incorruptible, it's the people who code it & use it who are so easy to corrupt?
The code and math behind Bitcoin is not susceptible to anything that we have today. It is not vulnerable. The people who are using Bitcoin on the other hand are vulnerable to a lot of things.
Example (of a unlikely scenario; probably a bad example but still): The majority could one day want a change in the mathematics thinking it is better than what we currently have. It gets implemented, Bitcoin ends up being vulnerable. Should we blame Bitcoin for this? No.
Most [well-written] code doesn't corrupt itself. It requires people to get involved, who, in turn, corrupt it. Bitcoin's claim to fame is taking people's corruptibility & effectively removing it from the equation (hence "trustless").
If not, Bitcoin's no better at being money than ordinary email/texting. As long as everyone is smart and honest, why even bother with crypto?
