Well I was humoring you, as in, let's say communism has never been done in the past. And all the other attempts were simply authoritarianism.

I already discussed that, the two nations that you commonly refer to as "communist" (USSR, China) are not the only examples of "attempts". Look at 1973 Chile for a counter example.

Even if you have a shot, to do it "the right way" it will lead to authoritarianism out of sheer desperation because it's impossible to make it work.

You don't know the definition of communism, so this is hilarious. Again, look at Chile's history, or Bolivia for that matter.

The free market is that invisible firmament that's holding all the things and stuff together.

First principles like this mean nothing, markets are not a law of physics, and communism and free markets can co-exist, therefore your point is moot.

If you break that amazing thing, terrible things happen, and I mean terrible! Don't break all the stuff cyberdemon, it's totally not worth it!

It's almost like you're not reading anything I say.

You could do a test pilot in your own household by shopping without worrying about math

Makes no sense, and has nothing to do with communism.

After a while it will catch up with you. That's the problem without knowing the value of things and stuff.

This is getting a little tiresome because of your lack of definitional knowledge. The words you're using are not congruent with their objective definitions.
