I can only agree with Hashy's opinion on that.
Perlite is cheap, relatively easy to obtain, and has a positive effect on root ventilation. However, it is not essential; personally, I wouldn't want to do without it. A good alternative is supposed to be vermiculite. However, I have no experience with vermiculite. Because: Vermiculite is many times more expensive than perlite. At least here in our area 😅
