I think you and I are on the same point for this so there isn't much point going further.
Probably not quite the same point - I think there's clearly some difference between paying for my meal and paying taxes, but I also think there's clearly some difference between paying taxes and paying a mugger (especially in a well-functioning society).
I just don't think the first difference is well expressed by pointing out that force is eventually involved.
That would entirely depend on how you feel about taxes and how you're government uses them.
As someone who's experienced both a muggings and police brutality I'm not really going to see much of a difference.
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".
