Namely, your theory doesn't work in more rural areas.
I've worked plenty of markets where there's spotty at best voice cell coverage much less the data capacity required for streaming. And the local economy doesn't encourage people adopting what's about as useless there as you claim HD is.
I could see selling HD radio to those people. I can't see massive boosts in capacity, selling tons of smartphones and having everyone walking around listening to niche streams with no local weather or news and sports.
HD at least allows different formats that may be of interest while enabling me to insert local content. For smaller markets, it's a better proposition than "let them eat internet."
Nobody in their right mind is anti-HD radio. The vast majority are anti-HD radio INTERFERENCE. If HD radio did not jam adjacent frequencies, there would not be a single negative post, except for a very few people who post about the poor quality audio.
You tout it as a solution for rural areas, and I have to admit, I've sat in a field doing a test of HD radio reception 70 miles out, every single station locked, not a problem - no need in my view for an FM power increase, because there were just a lot of cows and scattered farm houses around. Other people have reported reliable lock 84 miles out. How much more range do you folks need?!
The main problem for rural listeners is localism about affairs that affect their community. Small regional AM and FM stations that barely make a go of it financially and certainly couldn't afford the massive fees and upgrades that accompany HD. When you get out in parts of the rural west, there may be only one or two stations even receivable in the daytime, and nighttime brings home the folly of HD AM because the noise floor is horrific across the entire US on the AM band - largely due to HD AM along the Eastern seaboard. It shocks me, frankly, how well that interference propagates thousands of miles away, well beyond the range of the analog signal. To rural Westerners listening to things like KRVN Lexington NE or KTNN Window Rock AZ, the interference is unwelcome at best and enough to cut people off from vital news and information at worst. Of course somebody will always glibly respond - well you can get that on the internet. Poor rural folks in isolated farm houses might have dial up at best, if they even care about computers at all or have anything better than a 286. So internet is not an option - what is needed in the rural West is long distance, high powered analog AM, because FM just doesn't have the range to reach across hundreds of miles. Truly clear AM channels are the most cost effective means of covering hundreds of thousands of square miles.
As far as FM HD is concerned, there are already reports of distant FM HD stations hijaaking a local analog signal. Unfortunately for HD radio, the entire duration of this experimental system has been during a solar minimum. Once the solar cycle reverts to normal or high activity, FM skip will be back with a vengeance. Add to that an HD power increase, and the potential for FM interference is severe! 1000 W does not skip very well, but 10,000 does! So how about all of those high power HD stations in the West clobbering your station with skip - you will have an unlistenable situation because now there are three times the stations on the air (main plus two sidebands) coming in on skip. What a MESS you are advocating, and it is inevitable. Atmospheric skip WILL be back, it will be unpredictable, and the signal strengths will be enough to override local signals with HD from across the country.
Nobody expects WiFi to be immediately available in rural areas. But with both dials junked up with Spanish language chatter from over the border, HD hash, AMs on translators, and dull lifeless formats abounding - people like me inclined to DX before will put up with coverage gaps to "DX" by streaming. So what if there is a drop every so often? We are no worse off than we were with DX. And the rewards with streaming are access to thousands of streams instead of vastly over crowded radio dials with a couple of hundred choices.
