No, I'm not describing Roblox. Roblox is a great game and has many great characteristics, but this is bigger and broader than that. Sybil attacks would be detected in an open network first of all. If you can pull it off, I invite you to try: there's hundreds of billions of dollars on the table protected by nothing but cryptography and game theory. Knock yourself out. I'm sure all the people in this space are idiots and haven't seen the holes you claim are there. I'm old enough to remember when using a credit card was a hassle or seen as predatory on consumers and many people either refused to use credit or accept credit in their businesses. For several decades using a credit card wasn't any more convenient than using cash or check even. Over time, the scanners got better and faster, Visa and MasterCard integrated with ATM debit cards, and then mobile phones and swiping plugins enabled it all to get better. Now it's ubiquitous. But that ubiquity will make it all the more easier for merchants to adopt crypto. It turns out there is already crypto insurance protocols like Nexus Mutual and Cover that will cover you if a loss occurs. Insurance is really just a business problem that is easily fixable. On the plus side crypto is far more secure than Visa or MasterCard, because it works on public/private key cryptography and you simply sign a transaction rather than enter your name and address and all the same information you'd need to commit a fraudulent credit card transaction.
