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?
Yes,but all the bitcoin users have to freedom to choose not to use online wallets and store their bitcoins on their computers.But what if your computer gets stolen or broken?There`s no 100% security.

Where you scammed by some online wallet service?
