Esperanto has native speakers. Shatner is not one of them.

https://en.wikipedia.org/wiki/Native_Esperanto_speakers

> Native Esperanto speakers (Esperanto: denaskuloj [denasˈkuloi̯] or denaskaj esperantistoj [deˈnaskai̯ esperanˈtistoi̯]) are people who have acquired Esperanto as one of their native languages. As of 1996, there were 350 or so attested cases of families with native Esperanto speakers.[1][2] Estimates from associations indicate that there were around 1,000 Esperanto-speaking families, involving perhaps 2,000 children in 2004. ...

> some families have passed Esperanto on to their children over several generations.

My Esperanto teacher told me 'there are always a lot of marriages after Esperanto conventions '. It makes sense it would be the primary shared language of some couples

The Wikipedia article points out 'native speakers have limited opportunity to meet one another except where meetings are specially arranged. For that reason, many parents consider it important to bring their children regularly to Esperanto conventions'.
