That's a very pre-emptively defensive statement... Why doesn't HN like to hear this?

NAT makes it significantly harder to self host things, and as a consequence limits decentralization.

Which makes it easier for typical HN employers and YC startups (esp the social media kind) to stay afloat.

I've been downvoted in the past for pointing out what everyone says works in theory vs what actually happens in the real world.

NAT works for some use cases, not so well for others.

I know a database that's updated every night via a server-to-server connection that passes five levels of NAT, and when that crontab broke someone had to fix it by finding and correcting a bug in a 1500-line NAT configuration on one important router where the consequences of a mistake would be very bad indeed.

It works in the sense that the database is updated, but I cannot help thinking of Truth 3 in RFC1925.

Ok, but please don't bait the community like that. Pre-emptive defensiveness puts a negative torque on conversation.
