If you have a good seasoning then less oil while cooking is needed. If you have a new pan with a rougher surface then using a steel spatula will smooth out the surface texture and improve performance (without making it too smooth where seasoning won't stick).
There's a lot of varying advice on cast iron, but the prevailing wisdom seems to be that if you keep using it then the pan will improve.
Cast iron doesn’t seem to work as well on electric stoves: Temperature control is problematic. Perhaps induction heating would be more effective?
Fried eggs are just aldehyde cancer hell. There's so much out there you can cook without any oil and it's handy to know for sure. Try cooking stuff in sauces instead for example.

I also make scrambled eggs, but tend to use a tbsp (15ml) butter, but that is more for flavor and texture than to keep from sticking
Of course it's crispy, you are deep-frying your eggs in oil, like McDonalds-style fries. It may feel delicious, like almost anything overcooked with high temperature, but it is not quite healthy.
Just because you have drowning eggs in oil does not mean everyone does it that way.
FWIW it's pretty easy to fry eggs in a cast iron. You do have to oil the pan, but I wouldn't call it absurd. Just a dollop of oil in the pan. And the end result has a crispy, yummy texture that's hard to achieve with Teflon. It just takes a little practice and an open mind.
