I would say ~30% is not "fairly small". Also that 30% predominately works circa 9-5 and is disproportionately responsible for traffic congestion.

Plus, it's unclear how those industries get split. For example utilities, trade, healthcare, and leisure/hospitality all have a large number of office jobs. And cities have a higher concentration of office jobs than rural areas. I would be willing to bet that in most medium-large sized cities, half of all jobs could be done remotely.
