It is very easy to destroy lives with it as we can see in this case, and, making it harder to do so will work against the vary nature of this tech. This is a tough nut to crack but I think the space will remain filled with predators constantly baiting prey into the system with the promise of a big reward.
Every consumer ever has at one point or another wanted or needed to reverse a transaction. Chargebacks are a FEATURE of credit cards.
That's how I feel about crypto.
And it isn't just businesses who carry this risk. If a business was depending on a large inflow to make payroll, and that inflow gets reversed, the people who are expecting payment for their labor also are subject to a payment reversal.
There's definitely a lot of benefits to reversibility, but it has very real costs and tradeoffs.
