To make it more decenteralised. Cryptocurrency without enough participents actively voting with their computational power is not a cryptocurrency and will have none of the improvements over fiat currency. Bitcoin might have 51% dishonest problem but it can be made honest again by increasing total computation. Whether 51% are honest or not is function of total computation power [TCP]. Probablity of 51% being honest goes to 1 as TCP goes to infinity.
