The skin effect can be mitigated by, instead of a solid single core wire, using it in a litz wire configuration (several thin isolated strands, each strand acts as a single wire to reduce the skin effect by minimizing the cross-sectional area of each strand). Yes it will add volume, additional weight for the insulation, and due to it's additional complexity add an extra energy cost in creation.
But like most problems there are ways to work around them, if there is no economical alternative available.
