You're correct about the CNT, as I said, mistakes were made. But in many cases the rank-and-file strongly resisted and had they access to weaponry we might be living in a whole 'nother world
What's LESS threatening to the upper class and governments - a self sustained power buying anarchism into reality - or a "working class revolution" on THEIR territory under THEIR law?
Clearly you're right, I'm happy to say. My points still stand, tho. If you're successful, they will still come after your "anarchist" island community. And, at least with a working class revolution (especially one that reaches the ranks of military), workers can use their economic power to resist government efforts to crush them. Do you plan on buying a mercenary army to defend your island?
If I have to spoon feed you - obviously the island is less threatening. Buying anarchism into reality is really one of the more preposterous strategies I've heard. Still, it partly worked for the Zionist project so maybe you should look into that experience.
And do you seriously believe that an island, wherever it might be, will not be under the territory and law of some state?
