The point would jave been obvious if you'd read the whole message, including the quote of the post that was being responded to.
People are always posting about wanting smaller tick sizes - usually because they have the mistaken belief that it will make trading easier or more profitable for them.
Stocks now trade in pennies - but that didn't make most equity traders any more money and it didn't turn losing traders into winners. In some respects, it might even have made equity trading a little more cumbersome.
Same with reducing the ES tick size. When the "reduce the tick size" crowd find out they can't make money at a ten cent tick, they'll insist that the contracts need to trade in nickels or pennies.
I'm with nononsense - the tick size is fine but they could maybe increase the size of the contract.
