Sure, if you're only trying to protect against meteroids and radiation. But there's a whole lot of craters deeper than 2m on the moon. If you're trying to protect against the impacts that produced them, you do in fact have to be a long way down.
(Nitpick: those impactors are also meteorites, just big ones; the numbers in the paper I linked numbers are based on probabilities over time of an impactor large enough to get through shielding.)
Giant impacts are relatively rare - in the ~13 years of NASA's monitoring program, the largest impactor seen on the Earth-facing hemisphere of the moon left a 15m (inner diameter) crater [https://arxiv.org/pdf/1404.6458.pdf], and most have been orders of magnitude smaller.
Remember - the Moon has no active tectonics, no atmospheric weathering, and no water or other liquid evaporation/condensation cycle. The craters you see are an aggregate over billions of years, including some periods of much higher levels of random debris than currently (e.g. the Late Heavy Bombardment, which left most of the truly stupendous craters). In any given human lifetime spent on the Moon, you're unlikely to even be within visible distance of an impactor that can go through 2m of regolith.
