It's not a forced justification. That what was said before the game ever went to beta. I personally am happy they did it. Means the game actual has a challenge to it instead of being stupidly easy like the previous games. You actually have to put thought into what you are doing.
Good. Pay them your hard earned cash, give it all to them:)
DLC Rapid Rides, place it carefully though, as water is scarce $$$$$$$$$$
