It's hugely wasteful and ultimately not affordable, to build out such massive infrastructure that then needs to be maintained with taxes. Most cities have extracted the initial funding for this infrastructure: roads, water, sewage, storm drainage, sidewalks, overhead or underground cables from the developer. But the tax base can't really support that beyond the initial life for that infrastructure without raising revenue. All city and county fees, taxes, and fines all inevitably go up and quality of infrastructure still goes down.
And that's in cities. Extend it out to podunk and they have to be subsidized, even when they don't know that's what's happening. And it's getting bad enough many counties in the U.S. have started to revert paved county roads back into gravel because they simply don't have the money to maintain the paving. They're worse full of pot holes than gravel. And the locals don't want to pay their fair share which might mean a dozen families sharing 50 miles of road - it's the exact opposite of economies of scale. Their incomes obviously have not kept up with the cost of even maintaining local roads... but there's no market force that's really correcting for this either.
