I've had a look through your posts Happie Chappie and I can't see anywhere you explained to us why the unknowable Grexit scenario would be worse than more austerity - mind repeating yourself for my benefit?
A return to the Drachma, which would be subject to a rapid devaluation almost as soon as it was printed, would lead to parallel currency economy where those who have access to Euros (mainly the rich) would be able to get all they want and more while those (mostly poor people) are paid in almost worthless Drachmas.
The rich would simply hoard Euros - good money would drive out bad.
People paid in Drachmas would see their purchasing power plunge before their eyes.
There would be a massive currency black market (and likely a food and medicine black market too)
The gap between rich and poor would widen even more than it is now.
Those with Euros would be able to snap-up Drachma denominated assets at knock down prices.
The cost of imports would rise rapidly as few exporters would want to be paid in Drachmas.
The list goes on.
And that's assuming the Greeks could physically print and distribute enough Drachmas in time to prevent a complete breakdown of civil society. According to Varoufakis Greece doesn't even have any printing presses! They got rid of them when they moved to the Euro.
It's my opinion, and it's only my opinion, if Greece accepts the Troika package then the Troika will, in small increments, provide additional financial assistance over time. A carrot and stick approach.
Outside the Euro the only assistance Greece will get will be humanitarian.
It's not what I want by any means. Just what I think will happen. That's all.
Anyway, I don't want to derail the thread so I'll leave it there.
