At super sonic speeds the noise is awful so to make it simple the FAA just says "no super sonic flight".
This changes that to force the FAA to do the complicated thing and be like "okay in these locations at this altitude and this size plane" and "at these locations at these altitudes and that size plane" and maybe "never at this location" or maybe "only during local business hours " and we end up with a book of "well tailored" regulations. Which while complicated might at least allow for Boom to operate inside the US, which opens up a lot business.
This is perhaps a bad political environment to propose a bill that would let billionaires operate supersonic pleasure craft over the US, at considerable annoyance to 99.99% of the population.
For example, an SF - NY flight could be allowed to boom over northern Nevada, much of which is completely uninhabited. Right now it's completely forbidden over US territory.
