Cars always have moisture from short drives, should I change oil often?

Need to bring that engine temp up. Even if just sitting, 1200-1400 RPM to get the moisture out of the engine. Run for about 30 minutes. Then dump the oil and put fresh oil and filter. Oil will get acidic after a while even if new, so it's imperative to get that engine up to operating temps for a bit to keep out the moisture. Run it at least 1X a month. Change oil 1X a year. For whatever reason it can't go on highway ( not registered, etc ), that's what you have to do.

Stupidly Honda doesn't give oil temperature or pressure, just a basic on off of good or to low switch. But I can see that the coolant seems to be at temperature.
But that's why I don't really like the idea of a 2 year oil change. I'm fine with a year and a half on my second car that sits, but for this one I think it's still worth every year. I suppose I could replace the filter every other time if it's only a few hundred miles though. I just got some K&N Premium filters on sale.

The main thing is just how long of idling with the fans kicking on to clear out moisture? Only 30 Minutes is enough?
