#1: opportunity cost. When all of the incentive is to create paper value, many people who might otherwise have created real value don't. Since our whole economy depends on someone creating real value, that creates risk even for people who weren't party to the transaction.
#2: their money? Facebook didn't invent money. They got it by making promises to large investors and banks, who in turn got it by making promises to small fry. If 90% of the people whose retirement money went into WhatsApp don't believe that's a reasonable decision and wouldn't have condoned it if they'd had any choice, somebody got defrauded. It doesn't matter whether it was a series of little deceptions or delusions instead of one big one. The people who will be left holding the bag most certainly do have the right to sound warnings and issue complaints.
