Overall seems to give a good picture how Treconomics, but I think he is wrong a in a few ways. The first being private property. There is definitely personal property, but no private property as "business" like the Sisko Family Restaurant and Picard's vineyard aren't charging anything from what we can tell. They operate like their customers are family, and you're visiting them to eat/drink with/etc and then go home.
The second is his labeling of The Federation as a technically capitalist society. I don't think that's the case, as corporations don't seem to exist aside from the ones that are owned and operated outside of Federation space. There are family "business", but they don't have stocks or a stock market. And because the "businesses" that do exist don't charge or make profit, I don't think it can be considered capitalist.
And they are indeed credited to and debited from each citizen’s “account.” However, the average citizen doesn’t even notice it, though the government does, and again, it is not measured in currency units — definitely not Federation Credits.
I think this idea of each Federation citizen having a welfare account is probably wrong. I think it's more likely that it's just assumed that you won't abuse the replicators/transporters, with a set limit of how much of something a user can use it.
So you can maybe replicate only a handful of basketballs a day, a couple hundred hotdogs, etc. But there is an inbuilt limit to the machine and electricity provided to your home. But it's not an account.
Sure, I agree that there is absolutely somebody/some governing body controlling and tracking energy use. But again, no personal account.
As for the rest of what he said there, I am pretty much in full agreement.
