I think you have misunderstood what the other user was saying, and/or are not thinking through what you are saying.

You said "All areas should be nazi-free areas", but unless you are advocating for putting them up against a wall, that is not possible to do. That is what the other user meant by "'Tow it outside the environment' is not an option". By the way, I think that expression is a reference to this; it's not very relevant to this topic, but might help illustrate the point they were making.

Another alternative, like the other user mentioned, would be "lifelong reeducation camps"; but not only does that have questionable morality behind it, it's also not a view that merges very will with the idea of abolishing the police and especially prison systems, which so many on the left, especially the more libertarian left (which btw a lot of Beehaw seems to lean towards, including me, and I think the other user as well), subscribe to.

Like the saying goes: "don't attribute to malice what can be explained by stupidity/ignorance", or something like that; there are real life examples of former Nazis/white supremacists changing their views just from interacting with other people outside that group. When you think of a Nazi, you're probably thinking about the smart and actually evil ones that tend to be at the top, but a large part (I think the vast majority) are just the product of fear and ignorance (think average German during WW2); and when you try to erase/separate those people from society, one way or another, you're often just feeding into that ignorance and fear.
