For non-technical holders of BTC (i.e. the mass of the BTC population), the risk of inanonymity and centralisation still there: as they have to entirely rely on their wallet providers? If such wallet providers are hacked or meddled with their users, the users won't have anyway to protect themselves or anyone to make a claim on? Their fund in BTC is entire at the mercy of the wallets?
How you think BTC would work for the ordinary people in the future to replace their current existing financial assets and management with fiat currencies?
That's why we preached that get a wallet that you have total control of the private keys. Wallet providers always try their best to make it secure but we still have our responsibility on how to protect yourself from such malicious intent of stealing your coins. Used strong passwords, keep your private key to a safe location. We are our own bank so its up to us how to secure and protect it.
