| Oct 24, 2016 at 20:30 | comment | added | YCor | It can be shown that the $\mathbb{C}$-subalgebra $A$ generated by $R$ also satisfies the property that any 2 elements have a common eigenvector (because $R$ is Zariski-dense in $A$ and this property is Zariski-closed). Hence it is no restriction to assume that $R$ is a subalgebra. | |

Reformulated question so that it has broader interest
