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".
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.
Without wishing to take sides on the controversial issue of whether taxation is morally permissable, I would like to add that what I call "lawful taxation" is different from arbitrary confiscation. I call taxation "lawful" if it is collected according to rules that are knowable at the time is incurred.
