> There is a huge scientific merit of the algorithms for reaching a distributed consensus when not all participants can be trusted

Not quite. Distributed consensus had been solved in the 1980's theoretically and the 1990's practically, even in the presence of byzantine nodes. What Nakamoto consensus was first in was to extend this to the permissionless setting (at enormous expense & inefficiency, and with no benefits, in my view; though enabling large scale rule breaking or "censorship resistance", which some see as a benefit).
