This game is in desperate need of persistent progression content for main jobs...

I am well aware of that.

FFXIV, however, does not having long lasting content. Take 5.2 for example. If you aren't raiding Savage, everything can be completed over a weekend. And that's without spending the whole day on it. That's why this argument falls a little flat. Even if you aren't playing frequently, content lacks longevity. It isn't simply hardcore players running out of content. Back with 5.1 my casual friends were bored because there was nothing to do for over a month.

So while yes, people will run out of things to do faster than it can be developed. That shouldn't happen within the first week or two.

Hardcore players who run out of content and stop paying their subscription when they do must be in the minority. Otherwise, SE wouldn't make enough money.

Though, they probably should have a problem with that.

Why? There are obviously enough players who keep a subscription throughout the expansion. Just because some people run out of things to do, doesn't mean everyone does. (There are even people who run out of things to do yet still keep their subscription, but that's another story and their prerogative.)
