I agree with this specific point, remembering that is the same as lots of other ED activities. (but with a key difference)I think the issue is that there isn't just one problem with colonization, so there won't likely be just one solution to fix it. I don't hate hauling, but hauling for no real reason? That gets old fast. There's no real reason to colonize except to say you did it.
Example: Traveling to Beagle Point had no real benefit either, except self accomplishment and bragging rights. Key Difference: When traveling to Beagle Point, if a cmdr was careful and did everything they thought correct... after several weeks of travel they would accomplish what they tried to do. Success! After two weeks of travel they wouldn't eventually find themselves on the wrong side of the galaxy, so far away they might as well abandon the trip and start all over.
