What @laonie accomplishes is not typical. He has the advantage of using a lot of his own accounts in his trails and has been building up SP for months by automated vote. What he earns now is a result of all of that work. I don't think the average user would want to do that just to earn SP.

Rather than finding a new gimmick for SP accumulation, why not find more/better ways to incentivize powering up? We want more people to hold SP, not more ways for it to be exclusionary. Let's think of some new ideas for how SP can be used to the advantage of users and investors alike.

As i said I am new , but how can he earn  without creating posts. If he doesn't want to contribute how can he earn so much money

laonie also bought a lot of Steem and powered up. I doubt he'd be appreciative of having his investment pulled out of SP and into Steem. I know I wouldn't. 
Right now many of us who bought Steem for the purpose of powering up are having to rethink our strategy. I'm not complaining, because it may be what's best for Steemit in the long run, which *should* increase the value of our investment proportionately. But it's still tough to wade through since the *terms* of that initial investment are being altered.
IMO, the idea of stripping all *unearned* SP and turning it into Steem is a bit onerous and alters the original appeal of the investment far too dramatically.
There is a sense in which I like this though, if SP could float in value separate from Steem. An investment in Steem would be an investment in the currency. But SP would be directly an investment in Steemit, like shares in a corporation. Steem "earned" on Steemit could be powered up, but Steem transferred in would be subject to market differences between SP and Steem. 
Like you, I'm just thinking out loud. Maybe it has merit, but it's just off the top of my head.
Thanks for the cognitive exercise. :)
