(2) is axiomatic - and it's precisely the one I'm challenging.

Then formulate mathematically what your term "impossible" denotes so that we can deductively assess whether the sequence in question is impossible.

I hold possibility/impossibility/necessity to be logical states. An 'impossible' sequence/event is one that would involve a logical contradiction. So, for an infinite number of coin tosses (with two sides - heads and tails), an outcome which includes a reading of "six dots" or "ace of spades" would be impossible.
