I would never personally fund a road or library, even if it increased total social utility, as my benefit is reduced in relative terms
I don't understand this. Care to explain?

If there was no state (communism), black markets would emerge to provide goods that are cheaper to manufacture in collusion (firms etc...) as individuals cannot produce everything. In fact if the latter is the case i.e. individuals are expected to produce everything as is the case for the peasant - production will slow or even cease! As the pay- offs for the peasant are less than the pianist.
Black market why? The lack of state in communism is supposed to come after years of socialism, a lot of years. The idea of the socialist period is to prepare the new generations to a world with no state, thus avoiding such things.

Then again, such idea can be flawed by the concept of the evil human nature, defended by many people. I do not believie, however, man is intrinsecally evil, because in that case, I would admit absolutistism to be the best system available. Why? It's just a logic relation of ideas, and I do not need to explain them, my dear little Thomas Hobbes did it in his not so dear little book, "The Leviathan". I'm sure you are familiar to it.

And as for the cease of production, I don't understand your point.

This is like saying that America is not pure capitalist...
No, it is not, no place is pure capitalist, because such idea means the installing of total anarchy in the market...but well, we're not far away from that, I believe.

Yet, the main essence of communism is the lack of state. I seriously find no relationship between that and Stalin.

Besides this Communism goes against the grain of nature as it removes the hierarchy...
It removes classes, not the total organization of everything. In terms of production, there has to be an organization. Hierarchical, probably yes, someone has to direct. Unless of course, there is an alternative way of organization, and yet I do not know of any, nor do I know if Marx proposed it in "The Capital" (Haven't read all the book).

I must say I love that building!!
It looks like there was a guy hanging from the left hand side ... do you have an explanation for this?
Oh, it's what we call The Ovni. And that guy hanging, according to the source page, is an English student who commited suicide because the ancient philosophy classes had so many readings on really smart philosophers he felt like crap. According to the site, his suicide note was: "I just wanted to go to the cafe, but I was attacked by ancient philosophy readings and I felt like a zero, so I killed myself". Then his body was hanged there to give example to the other lazy students.

Yet in reality it is a doll put as a reivindication against some reforms the goverment wished to apply into universitary educations. I like the other story better, though, it's more interesting.
