why dont windmills spin on the vertical axis as that would be omnidirectional for wind?

    Here’s the specific bit relavent to OP’s question:

    VAWTs often suffer from dynamic stall of the blades as the angle of attack varies rapidly.

    The blades of a VAWT are fatigue-prone due to the wide variation in applied forces during each rotation. The vertically oriented blades can twist and bend during each turn, shortening their usable lifetimes.

    Other than the drag-types, VAWTs have proven less reliable than HAWTs,[20] although modern designs have overcome many early issues.

    VAWT = vertical axis wind turbine

    HAWT = horizontal …

      So TL;DR it’s worth the extra bearing for the added efficiency unidirectional wind flow allows.
