The net benefit to society when government is granted and/or authority is granted broad powers of surveillance is the abuse of that power to serve the desires of those in power rather than society in general. Your statement is carefully crafted to sidestep this with the wording, "...there exists criminal behavior that most reasonable people would agree is bad and should be stopped that may reach a dead end with services like Signal...", ignoring that the crime of abuse of power is far greater than any crime that could be prevented when it'd granted. There will always be "some people" that think this way. But more certainly such powers will be abused by those entrusted with them.
