For sure. There needs to be a cost charged by the exchanges (federally required) which decreases with time.

Nearly every symbol traded on exchanges trades with “price/time” priority meaning that the order that rests the longest at a price fills first. This provides a very big incentive to keep orders on exchanges for a long time.

The only time there is a speed race in these symbols to _place_ an order is when they are filling in a missing level. That is providing quotes at better prices. Why would you want to make that more expensive?
