I disagree that there is a monolithic "crypto community" that encourages scams. For example, a great deal of the Bitcoin community is fervently anti altcoin and many even consider Ethereum as a "shitcoin".
Regarding utility, everyone is entitled to their opinion. I disagree. There was a time in my life when I was "unbanked" and Bitcoin was the only way I could transact online. In the end, utility is subjective and it is not the government's job to decide whether something has utility or not.
