They didn't go full parler on them.
They had it worse than Parler. Not sure if you remember but they lost their hosting, infrastructure, DNS, payment processors, all in about a span of a week after the synagogue shooting.
What happened to Parler is a joke by comparison.

It's fine if you believe that. I prefer currencies because everyone would take it (flexibility), it resolves disputes about the value of goods, and allows people to make informed decisions about the value of goods.
That doesn't mean fiat currency is perfect (far from it). I prefer going to back to the gold standard or cryptocurrencies, but even crypto suffers from the fact that it's value is viewed in terms of fiat currency.
People don’t consider barter at all
They do, this is just one example: https://newyork.craigslist.org/d/for-sale/search/sss?query=trade&sort=rel
The purpose of barter is to replace the missing element of money.
Not even if it's missing, as evidence by the fact that people still barter till this day.
If both parties have mutual interest in what the other is offering, then money isn't an obstacle, so lack of money doesn't even play a role in this scenario.
For example, if you can buy an apple for a $1
If you tie the value of something to an existing currency, the argument for bartering is weakened, and it's just admitting that you're better off using a currency in the first place.
Bartering makes sense in many cases where both parties have interest, but a currency offers far more flexibility when either side isn't interested in the goods the other side is offering.
But why post this on c/Conspiracies?
It’s not like a central bank or national currency which you could sell at the airport or a kiosk at the mall for a real exchange rate
They were prisoners, what good would that money do for them in the first place?
Like I said, they got paid and they got amenities. They also had recreational activities (sports, a swimming pool), orchestra, library, movie theater, etc.
To recap: you went from believing in gas chambers, to believing that they were starved / worked to death, to finding out they got paid for their work and were treated far better than any other POWs in the war.
And there's still so much you don't know.
But I'll end it here because I don't think you're interested in learning about what really happened. As your first comment showed (starved/worked to death), you want to be attached to the mainstream narrative.
FWIW, I'm not even saying the Nazis were good people; I'm just saying that there's a lot of lies about them and what really went on in WWII.
Except they weren't starved / worked to death.
At best, you could argue starvation, but that was a result of the allies cutting off food supplies, and it wasn't the Nazi's intention to starve them.
As far as worked to death, this is just wrong. They had plenty of amenities in the camps and they even got paid for their work.
