You are correct in that technology implemented by well-meaning yet unsophisticated users is futile at best, especially when creating services that require strong security measures from the ground up.
Most horror stories center around lapses of users, admins and hopefuls that haven't done their homework. At the same time, it points to the scarcity and increasing value that bitcoin has - if it was considered worthless, there wouldn't be hackers and others out to get it.
I firmly believe that bitcoin will not be shut down as described in your article. I base that belief on the existence of other networks that continue to flourish, such as torrents, despite active measures at the internet level and legal avenues to restrict their activity.
Personally, I think the evolution of this hybrid payment-system-and-currency will go from exchanges transferring BTC (bitcoin) to other currencies to dying off all together as their services will slowly not be needed. As for governments not allowing such free commerce to exist, perhaps it would be a force to enact change - as taxes would become a more voluntary nature where we would only contribute to specific items that we actually need. (Instead of a flat 'fee' that is then distributed without the taxpayers consent.)
Bitcoin is a financial revolution that will change everything. Even if the current system falls under some unknown future threat, its existence has shown that there is another way to create a financial system that isn't dependent upon the failings of human decision processes and politics.
I don't agree with the article where he thinks it is inevitable that bitcoin gets squashed out of existence by collusion with banks and governments. I think it is more versatile than that, especially when users are given absolute power of their own finances.
