How long does it take to go from 51% hash power to 100% hash power? Once an attacker has acquired 51% hash power, is it possible to quickly get to 100% hash power by simply refusing to build on blocks created by other mining nodes and therefore discouraging mining entirely?

If 51% guarantees 100%, how quickly can this transition (from majority to total control) be expected to occur?
From What can an attacker with 51% of hash power do?


  Prevent some or all other generators from getting any generations


So, yes. However, it doesn't immediately give him more mining income. Once the block readjustment happens two to six weeks or so after the attack, the bitcoin network will notice that far fewer blocks were made, and the difficulty will go down.
