Like someone else mentioned, early game sc2 is a bit like rock, paper, scissor - scout too early and you'll be behind in economy against someone who's super greedy, but scout early against cheese and you've got a free win. You can take the "conservative" approach which is relatively safe against early cheese while not falling "too far behind" against a greedy opponent, but you'll still be behind in most of the games. If you're the better player though I'd argue it's still better to play conservative, be slightly behind, but win in the late game, while not falling victim of early cheeses.
