That's not what strawman means, and the point is that different measures protect you from different things and you shouldn't fault one for not protecting against others (outside its "threat model").

Paper dollars are designed to protect against counterfeit. That's all. To protect against muggers requires either a) sacrificing the desirable properties of paper dollars, or b) use of a separate security layer (vaults, safes, holding little at a time on you, etc). In no case are those limitations a failing of the paper dollar itself.

They likewise don't themselves protect against someone convincing you to give them your paper dollars under false pretenses. Same points apply: to handle that threat, you rely on laws, trust networks, escrows (like credit card arbitration) etc. Still not a problem with the dollar, just outside its threat model.

I made the previous comment in the hopes of compressing that point into one sentence. Perhaps I failed, but at no point did I misattribute a position to the GGP. "Your position implies X" != "you are advocating X" ... even and especially if you're not advocating X!
