Comparing a cryptocurrency to the network stack doesn't make any sense. You are cherry picking out of one layer of the network stack to make a weak ad hominem argument to support a bandwagon effect bias. Regardless, your argument is flawed by the fact TCP and UDP traffic are about equal on the Internet. That's two protocols at your chosen network layer, each doing what they are good at. Note: SHA-256 and scrypt are the building blocks of most cryptocurrencies. SHA-256 is to UDP as scrypt is to TCP? Dunno.
