Depending on what they are trying to achieve, whether pulling gil out of player banks, or to reduce certain server loads (or both) they could do what ESO does. Your first teleport each ~15mins is free, then the cost spikes up to a maximum value and ticks downward at 1 gold per second so that after ~15mins your cost is back to zero. Players teleport for free between any wayshrine as long as they use the wayshrine to do it instead of just teleporting from anywhere. People who want zero inconvenience pay a premium, people who will live with the inconvenience of travelling to the nearest wayshrine get free teleport. FF14 so far I havent found a mean to travel between major aetherites other than the teleport menu or map option, they could or should possibly look at maybe allowing aetherite to aetherite travel being free or reduced cost if trying to remove gil from the game. Or they could introduce flexible rates linked to the account level i.e. if you have a character at max level you have access to most gil making methods so prices are at their premium, while your highest level character is below the max you pay proportionate or some other normalised reduction in rates. Makes max level players who can make gil spend, and new players not get penalised by some of the ridiculous gopher questing the game is bloated with.
