I agree on your statement, that most people don't care about decentralized versions of anything including money. But one bad experience might make trully devoter of decentralization. Or some research. So yes, the projects like Libra can have more people actually using those, but while they will not be permissionless and decentralized, they will be missing the advantages of crypto.
And keep in mind that those projects will have regulators issues such as Libra and they will never be as decentralized as a project, where even the inventor is not known like bitcoin.
