Permanent /fly For A High Price

Currently the "/fly" command has a limited amount of time that you can use it before you need to purchase more usage time. That is fine and stuff, but I feel like it would be nice for there to be an option to purchase it permanently (unlimited use time) for players who are willing to pay a premium amount of petals for it. I suggest that this price be set at roughly 10k-15k petals. That is equivalent to 100+ hours of /fly time if you were to purchase it temporarily, which I feel would be enough to warrant getting it permanently.
