Because the argument isn't for regulation, it's against lobbying and it's against having a government that's influenced by corporatism/ capitalism (because that's largely what lobbying is).
Which pretty clearly makes the alternative socialism / communism, depending on how you want to define them.
Ok, I was reading that the alternative to current lobbying was to regulate the practice. How are you interpreting the "against lobbying" side of the argument?
Lobbying is about the right to petition the government; I don't see the direct line to socialism/communism, which is generally more concerned with the means of production. I don't think there is "clearly" a connection but rather one used to shoehorn a divisive and emotional topic.
