That's great that you've identified the very obvious service, but you've failed to identify the source of income. Who's going to pay for this service? Insurance companies? Bwahahahahah. Not a chance. Individual homeowners? They don't even pay for insurance. Renters? Nope. What about commercial? Those are also all renters, so why would they pay for something when they could piggyback off of any of the other tennants paying for the service? Landlords? Hell, they won't pay to for the most basic of service unless forced.
So you're panacea of if they build it, they will come isn't as realistic as you are hoping.

Amazon and SpaceX were not profitable when started and remained unprofitable for many years.
Our collective heart is in the right place. I have my own plans to do something about it but I am not in the same position as say Elon Musk for example. Not yet anyway ;)
I am in tech however. And I believe passionately that tech can solve this problem. Even if it is just a symptom of global climate change.
I think we must start solving these problems fast and with novel approaches. The same old tired routine isn't working. We've kicked the can enough down the road with government and fire prevention. New ideas and methods are needed and needed fast.
