There are plenty of organizations who by this logic don't. However they don't dissappear, even though we already have the tools available. If they're not capable of using the tools they have, why are they reaching for something substantially harder to do? There must be something else to it if they're not bothering to do what they can.

Of course power grants you that, it grants you absolutely anything you want, just like setting a fire gets rid of the rodents in your house, along with the house. That is exactly why absolute power is not to be assigned to any single organization, it can't be contained.
There is also the expectation like anyone using encryption for malicious purposes wouldn't do it regardless of any law, just like criminals carry illegal weapons. Only the law-abiding citizens could therefore be targeted
This pretty much solves a very serious problem for all illicit activity - secure communications. It's strange to argue that this ought to have no impact on the ability of law enforcement to combat organized crime or terrorism because they should just compensate elsewhere. That's waiving a problem away instead of facing up to it. Of course it's having a big impact, and telling them 'just be better elsewhere' is not gonna work, they'll still push for stupid legislation.
