Yes so that is the hub case (2nd half of my comment) -- clients will RST each others' connections then. Unless you are MAC cloning but not IP cloning.

A computer doesn’t send a RST when it gets an unknown packet…

Yes, it does, that is the purpose of RST [1]:
> As a general rule, reset (RST) is sent whenever a segment arrives that apparently is not intended for the current connection. A reset must not be sent if it is not clear that this is the case. There are three groups of states:
> 1. If the connection does not exist (CLOSED), then a reset is sent in response to any incoming segment except another reset. A SYN segment that does not match an existing connection is rejected by this means.
It's possible for a node to be configured not to do this, but this is the default behavior.
