Bases in mid-air are effective during a raid, when manned, as entry is all but impossible. Again, this base type is best for continuous habitation, but it is only slightly more protected than a house on the ground if nobody is manning it. Also make sure to put cobwebs all over the bottom to stop ender pearl glitching.
