For example, telling factories not to work with others, otherwise they will lose profits from their main customer (a much larger capitalist).

Of course, nothing prevents one economic agent from negotiating various additional terms before concluding certain deals, including those that have no direct relation to the subject of the transaction. For instance, a very common type of deal is an agreement on joint household management, accompanied by a condition of exclusive sexual services, and there is no reason to believe that in the absence of a state, deals of this type would be immediately wiped out entirely.

But, as we clearly see in the example of the institution of monogamous marriage, an exclusivity clause, even when clearly stated, is observed quite sloppily, yet not every violation of this clause leads to the immediate termination of the main contract. The fact is that the contracting parties are interdependent. Even if one party to the deal is significantly stronger, to punish the second party for violating the additional terms of the agreement, they would have to incur certain costs, and this would weaken them. Moreover, the direct damage from the violation of an additional condition may be quite small, or even non-existent, while the contract itself may remain very profitable for the strong party. In other words, empty tyranny is wasteful.

Therefore, the economically stronger party, although they may puff out their cheeks and demand special attention, will find themselves forced to turn a blind eye to the fact that not every whim of theirs will be satisfied; otherwise, their habit of petty vindictiveness will quickly correct the fact that they happen, by some misunderstanding, to be the strong party in most market transactions. Thus, through excessive arrogance, once influential companies sink into insignificance.
