Yes, you are right, only one nugget effect can be fitted. I fitted the variogram with one nugget, but still did not better than eye fitted.
If your criterion for "better" is visual, then you must be right. If your criterion involves minimising a weighted sum of squares similar to what gstat::fit.variogram uses, I would be happy to receive from you a reproducible example.
