The size issues are bandwidth and storage, not computation.  The law is not broadly applicable to bandwidth, and scaling will not end with the end of process shrink.  Moore's law will apply to storage in the near term, however, as it will be essentially determined by flash densities.  It appears to have enough headroom left to fully accommodate XMR.

I use the neutral term "size" instead of "bloat" because bloat implies the content does not add value, which I consider misleading.
