Hmm . . . if someone is falsifying their boarding documents, I think lounge access is the least of the airline's worries.

I always carry my SE card, but I guess the point is that AC has designed their policies around pedantic compliance and enforcement rather than from the customer perspective. What is the realistic level of probability of the status printed on a boarding pass not being accurate? And if it is innacurate, what risk does this present - one in five hundred passengers using the lounge who shouldn't be? Weigh this against the inconvenience caused thousands of passengers who are entitled to lounge access . . . seems like a no brainer to me. Anyway, what is the barcode for on the boarding pass? - scan that thing - surely no one can be accused of trying to alter than in their favour.
