OK, but the universally accepted term is democratic socialism, which is quite accurate. "Capitalism" implies a lot more than just free markets.

We are a social democracy in the sense that the current political climate and consensus is shaped by a few decades of social democratic rule. High progressive taxes etc are seen as norm and are of course necessary to finance a large welfare state.
However: How the money for a large welfare state like the Nordic ones is raised is orthogonal to whether it's being spent on a large welfare state or not. Had we had 10% military spending we'd have a much smaller welfare state than today, with the same taxes.
It's entirely possible for a country to have a very large welfare state without being the least bit socialist - especially if they have natural resources. If the swedish national mining Company (yes, a state owned Company!) suddenly found resources allowing taxes to be halved - we would.
The Swedish mining company LKAB is a socialist (state-owned) enterprise, however the entire economy is not composed of socialist enterprises, therefore it is clearly a mixed economy.
Relatively high taxes on their own are not "social" or "socialist".

There are already specific, well-known terms that capture the real problem with states like Venezuela or the Soviet Union. For instance, "command economy".
Only in the sense that "free-market", in this context, involves substantial government regulation of market participants and activities in the manner that "free-market" is usually, in other contexts, used to signal the absence of.
The Federal Reserve, bank bailouts, the government spending and government-backed monopolies that created the Internet we're typing on etc. The US "government regulates the economy or large pieces of it".
Also you attribute statements to me that I did not make, then say these statements you made up and attribute to me are wrong.
