Sir you are talking out of topic because everyone can get steem power as they have steem they definitely have steem power.
Steem power works as a powered up and it can be locked on the account.As I am Indian and my continent is Asian I can buy and sell steem at any time and at any place because if we have steem then we definitely makes it to steem power.
So my answer is definitely opposite to your question because we can buy and sell steem with the help of steempower .so everyone can buy steem and sell steem and also they can power up steem power with having a steem with them.
