You'd need a wallet with coins to spend to be able to do that.

The servers actually work by spending a fixed budget, which means the time between timestamps changes as fees change. Currently it looks like they're doing a few a day, but...

Ah, what you want is called a "random beacon" A good way to do that is iterated hashing, as Zcash recently did: https://lists.z.cash.foundation/pipermail/zapps-wg/2018/000337.html That's not a novel technique BTW: you...

No it doesn't: you could have chosen multiple blocks, and timestamped multiple messages committing to each one, then revealed the one that was best for you after the fact.
