Debatable.
It's not like we're "gorging" ourselves on XP... we're earning it by fighting, looting and doing activities like everyone else
You're too easily dismissing how hard it is to endure longer Blood Moons. True, we have more time to prepare, but that only accounts maybe for the first week BM (which is easy anyway). Once you go further in the game, even those who play at 30 mins can be fully ready and have shorter BMs on top of that.
You didn't consider ammo and base degradation in your equation: a longer BM, especially after the first few, means you need A LOT more ammo, and you could even run out at some point! On top of that, add the fact that zombies are continually bashing on your defenses and damaging your base, so unless you can reach and repair every damaged section, you have a higher risk of a breach, the more the night goes on.
I'd suggest you to try it sometimes, it's a different, less frantic, but more enjoyable approach to 7D2D.
You have an easier life on some aspects, and you can explore the world more, but you also have a tougher time on later BMs IMO.
