Currently building a foundation, or rather, slab, is about the most effective early-to-mid base you can have. A couple of trap doors 20ish blocks from each other and you spend most of your hiding time far from the trapdoors...z's spin on the featureless surface above you doing little to no damage.
For the extremely material poor, use an existing road. Great from night 1 onward until you get to ludicrous game stages.
So, yeah, why not foundation, foundation, foundation!?
