Scale change and regulatory change

The current and forecast growth in the number of satellite systems is putting strain on how the FCC and other agencies regulate satellites. There’s a lot of talk of regulatory reform, and calls for comprehensive rather than incremental change.

That leads me to wonder: are there instructive precedents where a step change in the scale of an industry or activity forced a complete restructuring of regulation; or conversely, where change in regulation let to a change of scale?  Perhaps there are examples where one might take lessons for the reform of space governance.
