Note that the definition does not take into consideration whether you think the victim should have done more to protect themselves, just as the fact that every year thousands of criminals are successfully prosecuted for stealing even in cases where homeowners did not have dogs, 24x7 security guards, etc.
Also the analogy that other person raised ("Your stuff can't be stolen. Period. A different thing is that you may suck at protecting your house") is a good one too.
However, we're talking about different things here.
When do bitcoins really get "stolen"? When terrible things happen, like if people install malware or trojans by accident, or don't apply security updates to their systems.
This, to me, is the equivalent of leaving the door of your house wide open. Not simply not putting an alarm system, you know.
That is, if you want to use bitcoin, have some common sense and minimal computer knowledge, first (minimal includes knowing how to keep your operating system updated, not be a certified sysadmin).

In that case, you should think more carefully about the problem because you're conflating two unlike things. Even ignoring the fact how many bitcoins have been stolen were compromised by previously-popular third parties, your current position is the equivalent of hearing about someone's house being broken into and saying “Oh, your stuff wasn't really stolen – everyone knows that you shouldn't buy a Kwikset lock/ever invite guests over/forget to arm your alarm”.
Designing a system which assumes humans will perfectly follow the best operating procedures is the security equivalent of hawking a perpetual motion device. In the real world, people delay updates or get let down by an unreliable updater, get hit by zero-days or suckered by scammers, etc. Anyone serious about building a financial system needs to plan for that and build in layers of safety precautions.
I get that you really want Bitcoin to succeed but the way to do that is by taking problems seriously and working to fix them rather than pretending them away.
This is a painfully absurd statement. You aren't doing bitcoin any favors by disingenuously suggesting that it cannot be stolen; everyone knows it can be, and faulting the victim for not properly securing their operating system (a feat that even billion dollar corporations often fail to achieve) is exactly the wrong type of message to be broadcasting to the masses.
So, if someone robs you at knifepoint on the street and takes your wallet, your wallet has not really been stolen, because you failed to wear adequate protective gear?
