Because the problem fusion reactors will solve isn’t free energy. We already have that, like you suggest. Solar, wind, geo thermal, hydro power, oceanic tide harvesting, and to a certain extent nuclear…all of that is free energy waiting to be harnessed.
The problems it solves include packaging (think footprint for a solar farm power plant), radio activity (like fission power plants), predictability ( solar, wind, etc), and location (hydro). Fusion puts clean power plants anywhere you want them, safely and reliably.
All of these allow you to advocate for a functioning power plant to governments and citizens without any drawbacks besides costs to build and maintain. It’s an easier sell than any other power in existence. It runs off of water.
