Personally I think an FTT (as in a material level of tax on nominal trade value, not the microscopic levels of current SEC etc. fees) is unlikely as no president will want to be responsible for possibly tanking the market. On the other hand, if momentum builds, Wall Street might actually get behind it: from the perspective of established players it's effectively a profit guarantee and permanent ban on competition, if there are exemptions for MMs and dealers as there almost certainly must be.
In terms of overall cost structure, more than likely it would just bring us back to 1970s-80s levels when commissions were much higher. Many famous traders and speculators were operating in those days and did just fine, in fact it's often said that markets were easier to trade back then compared to today. Day trading as such would go extinct but there would still be plenty of opportunity on higher timeframes.
