I didn't say there exist non-appropriate financial transactions.
So what is your problem with Counterparty, which is designed to carry financial transactions (but, in the mode of all such inventions, could be used for other stuff as well)?
I didn't say I have a problem with Counterparty.
Counterparty said it had a problem with what I and others consider to be reasonable limits, without explaining why (from what I've seen so far).
The 40 byte limit is very much arbitrary, and both Bitcoin and Counterparty would benefit if it were raised back to 80 bytes, because then we could store Counterparty transaction data more easily, elegantly and cleanly in the Bitcoin blockchain than we are doing now. 40 bytes is not just enough for our (legitimate!) use case. Of course, 80 bytes, too, is arbitrary, and the best solution is just to scale the fee with the amount of data so that the incentives all line up.
