I think you misunderstood parent's note. Taxing the nascent commercial space industry is an early move that will hurt its expansion. It's better to wait for the commercial entitites to be sucessful before throwing yet another barrier to entry in the mix.
Yes, there is one successful commercial space launch entity. That's hardly "an industry." Yes, there are many others who want to play in that arena, but none are yet viable let alone successful let alone profitable.
Air traffic controllers are there to guide air traffic, regardles of whether there are zero aircraft in the sky, or lots of aircraft in the sky, or a space vehicle launch or return. They do the same work, and it costs the FAA nothing extra when there's a space launch. They set up a temporary flight restriction (TFR) so the launch or landing can occur, and aircraft (other than scheduled carriers with filed IFR flight plans) stay out.
What's next - taxing boats because the USCG has to patrol exclusion zones in the water and constantly shoo away those pesky self-entitle Florida asshats who think they are welcome to come watch the launch from the water, and end up postponing launches due to range violations?
Our government isn't built on "user fees" which is what makes this unjust and inequitable.
We waste an awful lot of taxpayer funds on things taxpayers don't want. No tax is a popular tax, but taxing commercial space flight companies and giving NASA yet another freebie subsidy by any other name is disproportionate and unfair.
