Anarchist Catalonia, modern Rojava, more than a few pre-Columbian North American societies, the Paris Commune of 1793… Maybe read some theory instead of making arguments from ignorance.

And you can care about results without having historical results. Anti-monarchism in general had basically zero results post-Industrial Revolution until the liberals won in North America in the late 18th century, but that didn’t mean that they didn’t care about results, just that they hadn’t achieved much yet. The American Revolution was pretty quickly followed by the French Revolution, the Haitian Revolution, several more French revolutions, Brazilian independence, and eventually the October Revolution, the most recent Chinese civil war, the Cuban Revolution, and so on.

Between 1775 and 1925, the general concept of people voting on matters of statewide policy went from a relic of the Classical Era that had ended more than 1800 years earlier to the norm in North America and Europe. 1800 years of obscurity, then 150 years to ubiquity in the world’s wealthiest states and another 50 to expand to most of the rest.

Sure, anarchism has had a longer period out of the spotlight, not having been the norm since roughly the invention of agriculture ~8000 years ago, but you never know when it might return. Having a concrete, achievable plan to get results is good, but you also want to make sure that the results you’re striving for are just, otherwise you end up with liberalism again. And we all know how that ends up.
