The staking is primarily to fend against botnets. If you were following this coin, you would know that we've been fighting against - alleged - botnets, that were at one time mining about 90% of all generated coins.
Right now they are getting 0% of all coins.
Which scenario would you prefer?
It's not about pumping, it's about being able to provide BBP for everyone.
Then the pool operators are the ones you need to work with? Many different IP addresses mining to the same account and same worker, or even different workers, could be detected easily. There's no real need to require another buy-in to allow people to mine. I don't know how much or how easy it is to get the buy-in price or even what the price is/will be on April, but it's pretty crappy to require a "membership fee" of sorts for people to get involved in securing a block chain which is about Christian teachings. Wouldn't you agree?
