You can easily create as many wallets as you'd like, and keep your funds isolated from a wallet you use as an identity, if you wanted. There are multi-key wallets out there as well to retain control of your wallet in the event that one of the keys are compromised. I haven't used any of those personally myself so I can't really elaborate more on those types of wallets, but it feels like being able to lower risk is a solvable problem.
