The lack of accountability in btc is considered a feature. The fact that funds can be tracked at all is considered a bug, hence monero and zerocoin etc.
I'm no bitcoin fanatic but the number of scams out there that involve transferring money into a traditional bank account indicates that accountability doesn't solve anything.
What percentage of ransomware attacks involve direct bank transfers? I'm guessing it's minuscule. Better accountability might not solve anything, but it will certainly reduce the scale of the problem, which is generally the best we can hope for.
umm no... That entire purpose of bitcoin is to remove accountability, to make a digital version of cash that can not be blocked, censored, or regulated by governments or corporations.
