Let's look at this carefully. According to the scenario you've outlined, the "robber" has asked for my wallet, and indicated that if I am violent towards him, he will respond with violence.
It is not a crime for anyone to ask me for my wallet. Nor is it a crime for anyone to tell me they will shoot me if I attack them.
It appears I can simply walk away. Neither crime nor violence will have occurred.
A crime occurs when the robber threatens to shoot me unless I comply with demands he has no right to make.
On the other hand, an IRS agent telling you to pay your taxes has every right to demand that you pay your taxes, and will never threaten to shoot you if you do not. He will threaten to shoot you if it looks like you're about to physically threaten him.
You can put your theory into practice by walking into a bank with a gun (in states where it's legal) and kindly asking them to hand you a million dollars. It'd be interesting to see what happens next.
But, more importantly, it seems to be that your point is that crime is not a crime as long as it appears to not be one. As long as a robber asks and I cooperate, it's not a crime. As long as IRS doesn't use force first, it's okay to steal things from me. I don't agree with that. What right on earth does anyone have to take away from me the money I honestly made? Who gave anyone this right? Why should I comply except for the reason that if I don't, they will make my life difficult and will still manage to take things away from me? I haven't stripped anyone off their money, I created value and sold it to people who were willing to buy. Explain to me: why does anyone have the right to take money from me?
The IRS is not stealing from you. The money does not belong to you, it belongs to society, which has authorized its agents to collect its property.
This is the reality of human society. We are herd animals, and the herd has spoken. Your extreme anti-social views have not and will not prevail, for the logical (and observed) results are intensely undesirable to those of us who wish to live in relative peace.
Who makes up this society? Just the people in your political borders? What about the people in other countries? Or would they count only after their military successfully invades your country? And when their military does this, everyone in that country is responsible, right? Cause it's their "agents", right? So if it is an illegitimate invasion, they are all guilty? Or would the guilty just consist of the immature and irresponsible anarchists who didn't support any of the warmongers up for election? How would we know if it is an illegitimate invasion? Society decides, I guess?
It's amazing how the blatant conflation of state and society that you make is allowed to pass in debates about anarchism with such frequency. And how often the people who make that conflation pat themselves on the back for being all "nuanced" and mature when in fact, through sloppy thinking, they managed to avoid dealing with all the problems that the anarchist has had to work through in order to arrive at his position.
So if tomorrow the herd decided it is acceptable to send you to uranium mines to work for free for the rest of your life because it is better for the society, you'd have no objections to it? And, mind you, it is exactly what the herd had been doing for thousands of years, staying willfully ignorant of the horrors of slavery, religious wars and inquisition.
You are confusing acceptance of the need for laws and their enforcement with belief that law is infallible. This intense inability to deal with nuance is both a cause of Randroid philosophy, and one of its most aggravating characteristics.

And this is, I believe, why it's so comparatively common with computeristas; it is a worldview which is much more logical and binary than the current one, with the implication that such a worldview is obviously better. No nuance is necessary but there are no nuances to perceive in this system.
This is, of course, why the system is not suitable for general implementation. It will be quickly and immediately co-opted by those who can perceive nuance where others see only black/white, who will eventually bring the whole edifice crashing back down again.
