My advice for you, read all post first and then write your opinion after that. Don't just read the title and ask something which has been answered.
You are asking why OP saying this is a huge postive, and here is the answer
Without a doubt it won't happen forever and sooner all later all ICOs will be banned, and for good reason. For crypto thats a huge positive if we can filter most of these scams out, not that there isn't other altcoin scams, but banning ICOs is a huge step in the right direction.
