Just to be clear, nobody is saying that debt is always good, nobody is defending the present monetary system, comparing the present levels of debt and specially the way it comes about to slavery is quite accurate. Nobody is disagreeing with you there. I personally try to stay away from debt as much as I can as well.
The problem is that some justifications you are giving are objectively wrong, false. That is what the people here is trying to point out.

the problem is really debt for consumption, as opposed to using capital for production.
and I'd include government consumption here, often enough incentivised by central banks.
