In the QBundle Burstcoin Wallet, why is a fee of 1 BURST required to set the account info? The QBundle Burstcoin Wallet (v2.0.4, installed to Windows 10) requires a fee of 1 BURST to set the Name, Description, and Passphrase for the wallet. 

Admittedly, the fee is very low (worth about 2.5 cents at the moment), but why is a fee required? Who receives it?
You are claiming an address on the blockchain. The fee makes sure no one will (try to) claim all addresses on the network.
