I know you're sincere, but I kind of had to laugh. Reinhart and Rogoff have been through the ringer for publishing that paper, which is almost entirely bunk. There was a huge storm that made it even to the mainstream media about how truly flawed that paper was (with errors getting as basic as "they can't use Excel.") It's even mentioned in the OP.
To be fair, the claim that slower economic growth is correlated with high debt is somewhat true. But most argue causation is in the other direction: slow growth causes high debt.
> I admire the candor of your second point ("we just inflated it away.")
You might recall that the time period in which we inflated that debt away was one of the most prosperous for all Americans.
Meanwhile, austerity will directly lead to people losing their jobs and an economic slowdown that will prolong the suffering people are already going through...for what?
