The biggest hurdle to Bitcoin adoption are on-ramps / off-ramps. Businesses and individuals dealing with Bitcoin frequently get de-risked by banks and suppressed by regulators (e.g: China & India).
Libra if (a) can be interacted with via API, (b) can itself be acquired via bank transfers / credit cards & (c) not geo-fenced, will eventually be adapted into one of the many exchanges and will contribute greatly to solving Bitcoin's on-ramping issues.
Whether consumers want Bitcoin once they've tasted Libra, well that's an ideological choice. It'll be interesting to see how it plays out.
