Try to dodge the tax man for enough money there will be gunmen at your door to take you to prison.
Eventually, yes. That's also true if you try to dodge your local restaurant, after availing yourself of their services.
Of course the practical inability to refrain from "using" government is a big difference! But it needs to be included in the analysis - it is not as simple as "if you don't pay, there will eventually be force; ergo it is robbery".
I just don't think the first difference is well expressed by pointing out that force is eventually involved.
As someone who's experienced both a muggings and police brutality I'm not really going to see much of a difference.
I think it is a necessary evil for the most part but I still hold the opinion it isn't something you get a choice in.
