Your natural gas price (if correct) is much lower than the national average, and even much lower than your regional average. Average natural gas prices in the US for Dec 22 were $1.67/therm while average electric prices were $.17/kWh. Here's a great chart, with regional values also: https://www.bls.gov/regions/midwest/data/averageenergyprices....
I think you are right though that much of the "hype" is based on avoidance of fossil fuels rather than straight economic advantage. The hope is that eventually the electric grid might be all renewable energy, while the efficiency of burning gas doesn't have much room to go up.
As far as economic advantage goes, keep in mind that carbon emission famously is an unpriced externality. Everyone's given up on trying to put carbon pricing into place to make the economics "naturally" work out, but in a world where heat pumps and methane gas have similar to-the-consumer pricing, the true cost of heat pumps is lower.
