So none in the senate were able to publish some support to Libra despite facebook hiring popular lobbyist. What they got for now is the Coinbase CEO, they got a long road to walk. While China is already miles and miles ahead in digital currencies.
Coinbase CEO's opinion on the Libra cryptocurrency doesn't really matter and will have no effect or any way influence most members of the crypto community's stance - and that is to shy away from Libra as possibly as they could! Moreover, maybe he did announced his support to Facebook's Libra only to please Mark Zuckerberg since we may not know if he has any other hidden agenda being a businessman himself.

With facebook's Libra launched, Coinbase will also benefit since people will also be registering to them. People will credit cards will go to the platform.
