Ethereum addresses scaling with a flexible block size system, which is only a temporary solution. Long term, the ethereum community is heavily involved in "scalable blockchain" research, the only true solution to this problem. As for coins getting stolen: Ethereum users regularly make use of "bank vault" smart contracts that can time lock funds as a protection against thefts. As for people doing "naughty things" with Ethereum: No, there is no central entity that maintains "anti money laundering" information on transactions.
