You raise legit concerns. Though the practical degree to which recourse is available and the effectiveness and fairness of those reversals really vary depending on where you live and/or transact. In a headline-grabbing caper like this the advantage seems obvious. But from the less sensational, day-to-day perspective of a small seller, reversals can be a nightmare ripe with fraud (google "chargeback fraud" for anecdotes) infeasible to pursue. It does put onus back on the buyer / investor to do some diligence on who they buy from or send their money to, and increases the importance of reputation in the space. (I personally feel there's an opportunity right now for a reputation mechanism to complement the crypto economy and believe when that catches up it will help incentivize good seller behavior). Kind of like when coins were primarily used as a medium of exchange. Coin payments didn't have reversibility, and adjudication stayed within the purview other institutions, i.e. courts, instead of being diluted and delegated to e.g. VISA. A more efficient dispute resolution system - some kind of analogue of the legal system civilization has built up over centuries - is another opportunity I feel is ripe for innovation in connection to the crypto space. I do think the missing gaps of reputation and justice will be filled eventually and adopted by users, which would go a long way toward addressing your criticisms. In the meantime existing options of criminal / civil litigation remain available and people sending large sums of money would do well to make sure they know who they're sending it to so they can pursue if things go sideways.
