You can always spend 25$ today and acquire 500 bts for the fee. Or make a steemit post or two and trade it for bts to cover the fee.
The fee is there to make sure there is no squatting, enacts a member fee which covers lifetime membership in the BLCA (BEOS Limited Cooperative Association) which is a non profit organization that BEOS holders get to vote for Directors - Block producers and wp's.
The fee also helps cover the substantial costs bore by the BLCA to create the technology that allows this all to happen. EOS accounts are around 3$, give you a long gibberish name. Short accounts and custom names are auctioned for thousands of dollars. A standard fee allowing you to reserve any name you like seems reasonable in comparison.
A bts lifetime account is 3000 bts. For that you get lower fees. BEOS based BTS can be sent and received for no tx fee.
