I thought it would be cool to have my own TLD, but apparently it’s all managed by the ICANN, so you can’t just name your website with any TLD you want. There are different prices. But at least you can customize your second level domain. Why aren’t TLDs like this?
DNS isn’t just an address book, it determines ownership. So in a decentralized system I could just spin up some servers that direct anyone in my area trying to reach PayPal to my IP instead.
