what? 

“us” is the network of peers. if the network of peers can be bribed to ensure bitcoin fails then bitcoin was doomed from the start

part of bitcoins security design is to assume the majority of the network are honest nodes and bitcoin uses the longest chain of work. it’s in the whitepaper

if all of us can be bribed with cheap deals humanity doesn’t value hard money enough to protect it.

now if some of us try, it will fail, which is what happened to bitcoin cash and countless others
