If difficulty of selecting and implementing a strategy is part of the tradeoff (so that more complicated strategies count as "worse" because of their difficulty, even if they promise an otherwise superior outcome), maybe there are "best" strategies in some sense, like there is a biggest natural number that you can actually write down in 30 seconds. (Such things would of course have the character of particular decisions, not of decision theory.)
There is not a biggest natural number that you can actually write down in thirty seconds -- that's equivalent to Berry's paradox.
