This may be one of the good cases, then. I'm not an expert in cancer but I am a biologist and physician. The head and neck cancer (here) and various pediatric indications get the most attention but it has felt that proton therapy has been seeking an indication for almost 40 years now.

The study was designed to show non-inferiority, which doesn't preclude their ability to show an improvement. It would be helpful to see other studies before determining that proton therapy is better (or even non-inferior) to radiation therapy. It's certainly much more expensive, which shows up in the study as many subjects being denied insurance coverage.
Edit: This is now in the weeds, but the per-protocol participants didn't fare better than the intention-to-treat participants, which one might expect since insurance approval lead to dozens of subjects changing treatment arms.
In Europe at least, many insurances cover it if you have the right criterias.
From my visits, they mostly focus on children that have some very nasty cancers, the IBA hospitals are all designed with children in mind (to avoid stressing them), and from my memory, a unique hospital is often enough to treat a whole country for the kind of cancer they target.
Now, if it is on par with classical radiotherapy BUT it gives less subsequent problems, it might be worth the cost as subsequent problems can be as expensive or even more than the original treatment. It becomes an actuarial issue to know where is the tradeoff.
