I've played a few more games on deity, and for those who are struggling with era points, my best advice is to maximize on great people to whatever extent you can. You get +1 era point each time you recruit a great person. If you can monopolize great people to any extent, you can generate a ton of era points especially during golden ages when it is otherwise hard to generate them. I have been able to chain golden ages on deity by having such strong great person generation.
This was easiest thus far when I played as Gorgo. If you play her properly, you can generate so many great writers you can't use them all. But it will give you a crap ton of era points as well. You can do this to a lesser extent with most other civs, just have to use Pantheon of Divine Spark and spam theater districts asap in new cities. It'll just take longer with most other civs.
