Absent subsidies (whether provided by a government, employer, religious order or other specific community), I’m honestly not sure how a safe, sensible, desirable product can be delivered at what anyone would consider a reasonable cost.
I grant that there is probably some room in there for in-home child care that probably more closely resembles a hobby business than a true commercial endeavor - I can see zoning type issues being completely determinative on whether child care at this scale is feasible or not. But I also don’t think those are the types of arrangements that the author of TFA was really describing.
