You don't craft things? Or use chests? Or furnaces? There's lot of reasons to want a safe shelter, it's not just about beds. Also, while I can see the appeal, stone brick vs dirt has never made a difference in Minecraft.Quote from KyoShinda
Well, the new bed mechanics make building in survival virtually pointless now. I would prefer if making a shelter out of stone brick vs. dirt would keep me safer. Not only was the system still behind, but now it is down and out.
Besides, anything more elaborate than a crappy box-hut or cave has always been optional, and barring a massive gameplay change, will always be optional. If you built anything like an actual house in Survival before, you still have 99% as much incentive to do so now.
