Absolutely, there are different reasons for it. Maybe a 4-bar loop is a bad example since, as you rightly point out, getting stuck in a loop is commonly due to lack of songwriting chops and is a more technical skill that needs to be practiced.
On music production forums I frequently see people comment that they've been working on a track or album for years, they're just trying to get it perfect before they finally release it, so they're constantly doing tweaking to what's already there. That kind of behavior definitely indicates fear to me.
