If one has a ontology strong enough to handle paradoxes one can have time flowlyness from non-copenhagen sources by having meta-time and meta-time evolution even if the (“historical”) time would “stay still”.
J.W.Dunne famously bit that bullet.
But if your side is allowed to embrace paradox, so is everyone else’s...so that there an no lomger any wrong theories of time.
While the time travel paradoxes are derived from the logical paradoxes, if you have a theory that unambigiously says what happens it can be contradiction free even if it has grandfather paradoxes. There can be theories wrong about how a game of Achron will go.
