It would be. But the community at large, not just the star wars one, thinks recasting an original production piece is OK. Of course, some collectors disagree as it devalues their own collection but they are a minority. The issues pile up when recasting another recast like the CFO/JoeR in recent discussion or an original sculpt.
CFO and JoeR worked together to mould and cast a production made helmet that JoeR owns. Community belief says only CFO and JoeR can say who gets to make additional copies of "their" casts.
