Definitely, but I think conflict of interest is only part of the problem. Many companies and contracts are vague and open to interpretation. The problem is that there is no way of arbitrage when a dispute arises.
Sure there are ways (formal and informal) to have disputes arbitrated, it's just that 1) the amounts involved are utterly trivial so it's not worth the time and expense and 2) many Bitcoiners value their financial privacy more highly than they value whatever amount is at stake.
