Trust may not be necessary on paper but it is a huge competitive advantage, and a strong distrust is a total dealbreaker for most potential business partners.
Trust is vital in a business relationship. Contracts are a useful backup against a legitimate body, but they are not much use against someone who has literally a proven track record of going on the run from law enforcement.
Please don't downvote /u/ThePadawan for this. It is an important foundational question. It is a hard question to answer in the same way that "If you're forging steel, why are you talking about iron crystal structures in the first place?" is a hard question to answer.
I'd be keen to read an answer from someone more articulate than I.
Enforcing a contract is often not worthwhile.
