The issue of sidestepping future interactions is that such a schema has no meaning. If I go a step further and stipulate that the transaction doesn't need to be proven to third parties then having any schema bar making the transaction itself is completely meaningless!

It is only when you attempt to prove or sell the claim in future, to third parties does such a schema and blockchains have some utility.
