Yeah but that is a bit of a strawman, especially if it makes you believe that is the actual goal of competing cryptocurrencies. I mean there are probably some people that say this, but a lot of the cryptocurrencies I've been into, they want to replace the whole system, not just the dollar, but banks, financial institutions, law institutions (with smart contracts), corporations/organizations (with DAOs), exchanges (with DEXs), they want to bring a solid money to the unbanked, and bring it to IoT devices, they even want to change the internet itself! And Steem is included in those.
