If you're an individual or organization in opposition to a state / stage agency then certainly it makes sense to find an app to protect your communication without a third party being involved. Short of that, consider if you actually need "P2P encrypted messaging" - if you're doing business-type things then you should probably use a business-type messaging solution. Slack is pretty good. IRC is fine if you're slightly more paranoid, it just doesn't have UX on par with a commercial solution. Find any HIPAA-compliant messaging product and you'll get most of what you actually need (vs think you want), but be prepared to pay much more for it than for a regular chat client.
