There is a degree of difference between cooperation in day-to-day usage of
the system and cooperation in the rare cases the system has a bug.

Distribution by consensus is inherently a fragile system. The network will
continue to break again and again as long as programmers are fallible. But
the types of bugs that occur will change over time as we learn the best
practices for maintaining the system.

Altruism is a facade that hides other motivations. The party cooperating
with the miners losing money were doing so to maintain good relationships
with those miners and to make sure those miners stay within the system and
not attack it.
