It makes perfect sense exactly if you start thinking about energy as something that will eventually become dirt cheap and plentiful. Current market prices for electricity are have been coming down steadily for some time now. Mostly consumer prices are lagging this because we're still paying off obsolete energy infrastructure put in place decades ago. But basically, there hardly is any variable cost with wind or solar (+battery); just fixed cost for putting the infrastructure in place. Economies of scale, improved production processes, innovations in using cheaper materials, improvements in efficiency, etc. are driving prices per kwh down.
So when it comes to vertical farming crops like wheat, it's worth looking at when that price drops to "low enough". Really what we are talking about is the cost of the infrastructure needed to perpetually produce enough energy for the life time of the indoor farm.
And you are right that cheap, plentiful, clean energy will have lots of other interesting applications. IMHO, that's going to be the story of this century. Solving this will produce a new economic boom very much like oil/coal caused last century. We can solve a lot of issues with cheap energy. There are a lot of things bottle-necked on energy cost. Improvements on that front unlock new applications.
