you do actually make a good point, but many of my views I feel are INHERENTLY pragmatic or at least are more strongly grounded in reality than most alternatives; when it comes to if they will ever be implemented, perhaps not (that would require certain conditions that are not present right now), but i'm not that unrealistically optimistic and imprudent to know that they don't tick off a lot of people (i don't talk about them to many people)
in implementation, they would likely be quite effective (i wouldn't believe them otherwise), but expecting them to be implemented is not realistic (given current conditions), nor is it anything i do; i would have conceded that without you even pointing it out
when it comes to things like anarchism and obviously marxism, it's a joke to say that they would be effective in implementation. libertarianism i don't really know
