lol, sorry about that! I'll try to reword it

Essentially the social surplus of a transaction is how much society benefits because of that transaction, so if McDonalds sells a hamburger, you compare all of the benefits of selling that one burger, like the jobs it provides, and the fact that someone ate that burger and is no longer hungry, and subtract from that the social loss, which is the loss of health in that person, and you have the social surplus.
Now in economics there's something called the law of diminishing return, which, in terms of that example, would be the social benefit of the first burger is going to be more than the second, and so on and so forth. So that's where we come to the marginal social surplus, which is the added social surplus of one additional burger, like how much more benefit is there if McDonalds makes 4 burgers instead of 3. When the marginal social surplus is 0, then McDonalds making more burgers will actually hurt society more than it helps, cause at 0 it has maximized it's potential social surplus, but that only purtains to at that current point in time, and situation in the market, and with a slight change in the market, or a change in McDonalds could change that, and them selling more burgers could help society more, like, if they donated a certain amount to charity every thousand burgers eaten, or something along those lines.
All transactions have an aspect of social surplus or social loss, and the vast majority have social surplus, but even in the case of social loss, the government intervention will almost always cause more harm than good, and more harm than that prevented transaction.
There are a few laws in terms of commerce that are neccisary, and those are the ones that keep the system stable, such as antitrust laws, because those have been repeatedly proven to cause more good than harm.
To really show how government hurts the economy I'd have to show you all sorts of graphs and ****, but the long and short of it is in markets, as in life, everything is determined by supply and demand, and where supply and demand meet is called equilibrium. Governmental intervention screws with the equilibrium, and causes the amount purchased to be not the amount desired, and not for the price desired, and in the end it just hurts everyone involved.
And with institutionalized socialism it sets up a system where everything has governmental intervention, which screws with every single equilibrium out there, and thus it cannot work.
Now it's completely different if it's a social socialism, with no laws dictating that it has to be a socialism, but the people just choose to live in a socialist society, because there is nothing to say that that can't work.
But once the government gets involved, that's where the problems arise.
