The value of a volcano is tremendous in energy and views. The energy is tremendous alone. The rising heat provides many homes with energy and also burns many homes up.
The most obvious thing before that is all the trees. In time they will all be destroyed by bubbling hissing steam and orange lava!
In economic terms it provides the most utility for all stakeholders to harvest the trees as soon as possible. Cutting down all the trees on all active and dormant volcanoes like Mount Rainier will only effect views from close up.
The surplus in lumber will drop home prices and allow more middle class families to own homes instead of renting. I'd rather see a middle class family in a home close up, than a tree stump far away.
Active volcanoes provide the best views, from close up. Lava has always been a crowd-pleaser. Everyone one has at least imagined it, leaping from cushion to cushion, quickly and carefully.
The older generation will pay more to throw electronics in the bubbling lava then any analyst would ever forecast.
The ash after an eruption will improve the soil, and we would have no trees without good soil. To build a safe community you need to start with the ground up. That is exactly why the ground near active volcanoes should be opened for tourism, logging, and affordable lava side housing.
