You're right. Tactically, though, that only matters if you litigate the contract. 99.999% of contracts will not be litigated. There is business value in non-litigated contracts: if there wasn't, they wouldn't ask for it.
Accordingly, if someone asks you for a contract, you always get something for it. Handshakes are free, formalized promises five figures and up up up.
[Edit to elaborate: Most importantly, promising to do something you intend to do, or promising to not do something you do not intend to do, are not valueless. I have no intention of working for e.g. Zynga. If a company wants me to durably commit to that, though, the fact of the commitment has nonzero value to them. Even that easy to keep promise of locking in my behavior in the event of something unlikely to happen costs money.
This goes for pricing for megacorps in any circumstance, by the way. If you normally get to email in 24 hours, and they want that formalized as an SLA, that should cost an appreciable amount of money. No, not $100. $100 is appreciable to you, but if they can spell SLA, they lose precision under five figures anyhow.]
