Facebook as a corporation has a lot of power, but the main question - Do the people want to buy Libra? People buy bitcoin because want to control their money personally not with help of banks or government. People don't believe them and Libra will be 100% controlled by government. So, we need this feature? I assume that no.
I also think so. Libra will be fully controlled by the government because Libra is a centralized currency (therefore I don't want to adopt it). But people might buy Libra because of the ease of payment such as insurance, electricity, water, etc. And traditional payments using fiat will soon be abandoned.
