Given differing aptitudes for solving different problems, the comparison might be moot. However let's say an individual is equally competent in both areas, and let's play the devil's advocate for a minute. No matter how successful you are at creating utopia, there are many more people that have an interest in engineering the failure of both you and your creation, and each one of them is a human that is potentially as capable as yourself, if not more so. They will collectively outlive you, their efforts will be relentless, and the knowledge that they gain in undoing your work will also be passed down to future generations. With that in mind, the relative worthiness of efforts might not fall hard to the side of solving political problems right at this instant.
