The 'easy mode' is incredibly hard at least partly in terms of nobody else having the capability to finance it (with the possible exception of two superpowers and Jeff Bezos)
But yeah, I tend to agree that whether it ultimately succeeds or not, blowing Starship up is a "fail fast" strategy because they have the money (and the reputational capital from successful Falcon 9 launches) to learn from their mistakes that way, and not many others do. Much as the waterfall approach of big space projects gets derided, there's a reason entities that can't take the reputational hit of visibly blowing stuff up on a regular basis do it that way...
But this 'easy mode' is still so incredibly hard that nobody else will even attempt it.
I'd love to see some serious competition emerge in the reusable rocket space, but SpaceX is far, far ahead with Falcon 9 being an incredible success, even if the Starship project may be headed for failure. Nobody reports on 100+ successful Falcon 9 launches/landings in a year, those are now mundane. But a small number of Starship failures - test flights of an experimental vehicle - become big news, mostly because they involve spectacular explosions.
It seems that Starship may be too big to 'fail fast', mostly because of the visual spectacle of those failures.
