because bitcoin i just a wallet
Steemit acount i san account that requirs more than just sending and receving steem

anyone can have a steem wallet u can signup for poloniex or bittrex and havea steem wallet
but a steem account is more than a wallet!

I am pretty sure thats why!

The thing a steemit account can do costs money on our blockchain! if steem was free or worthless like a testnet u could do it all free but they made steem have value now! so your account needs the 9 steem to be created because of the way steemit works!

Its not easy to explain to people , theyll assume it is a major failure of the system
