Ofc he has no issue with syndicalism, its merely an accumulation of common sense.
You can see it in his chat with peter joseph back in september for example. There has to be admissions that plain out anarcho-capitalism will never work, quite simply put, its nothing more than idealistic intellectual fantasy for educational purposes and not a SOLUTION.
There are numerous barriers to purist anarcho-capitalism, basically short of divine intervention it can never come about, because it has a monetary system that is flawed as it currently is, so again it quite simply cannot exist, its impossible.
Anarcho-syndicalism is as close as you can get to an ideal scenario in todays world, simple as. Not only that but there is living proof of it in action in mondragon.
Anarcho-syndicalism is not a solution either, merely a logical next step towards improvement/evolution of our social/economic/political model.
Capitalism is ownership of the means of production with a belief (and belief is the important word here) that the hidden hand of free markets will balance it all out.
Stefan has yet to explain how the carte-blanche situation is to come about short of some kind of divine intervention, so what are you left with as a REALISTIC improvement on our situation today without forcing people to do anything, without voting for change we all know will not come about?
A-S is about making everyone self employed and a direct and equal shareholder of the means of production and also a direct equal controlling voter of what the profits get spent on both business wise and social wise. Its not perfect or utopia etc etc we've been over that a thousand times now, merely a model towards change for the better.
It sabotages the system because it exploits the loophole in the system which biases towards incorporated entities and makes the current rep democratic system irrelevant. There is NOTHING Stefan can say against a system which is proven to work because there is no theory at play here, its a living factual example in mondragon. He's standing on nothing more than thin air and ofc he knows it, you can dream about what is ideal from now til doomsday it will change nothing. Man did not go from fire and the wheel to putting men on the moon overnight, nor has he got started yet IMHO, if certain barriers were removed such as the current FR banking system or a monetary system entirely then he will most likely evolve into a completely different creature with different belief sets and abilities. Such a creature would be a God to us IMHO, capable of perhaps moulding entire solar systems and ultimately galaxies to his whim because the only barrier he would have to overcome is the limit of his own imagination and resources to hand...actual physical resources instead of make believe self limiting monetary resources. At the moment we are infants in the nursery learning by gaming each other and for personal physical gain.
Intellectual and spiritual gain is something we are hundreds of years off getting a peek at yet IMHO.
I will never live to see it and IMHO things will just continue to get worse until we learn our lesson but its going to have to be the majority of people on the planet who have to come to this realisation and we're talking billions. Technology might speed it up but I'm still pessimistic about the speed given that humanity as a whole seems to only progress through pain - substantial pain - before 'getting it'.
Understand that there is nothing wrong with Stefans anarcho-capitalist outlook from a gaming pov, provided all the players play by the same rules, its pretty obvious you're not going to have that as cheating is part and parcel of gaming
