Why Does the THAT Blockchain Have Transaction Fees?

The THAT blockchain will incur 'near zero' fees on transactions (applicable to the sender). Since every transaction published on the blockchain imposes on the network the cost of needing to download and verify it, there is a necessity for some regulatory mechanism, typically involving transaction fees, to prevent abuse. Transaction fees help reduce spam transactions that may harm the network and protect blockchains from being flooded with malicious transactions that impede legitimate usage. The fees will be set as low as possible to be considered insignificant to genuine users of the network, but high enough to deter malicious users or load attacks on the network. Transaction fees are also paid out to individuals who help run and maintain the security of the network.

It is important to note that brokerage fees incurred when buying and selling THAT on an exchange are entirely separate from transaction fees.
