The funding for meta-EA still seems to potentially be a bottle-neck in the short term. This is because there are many people who already care about the concrete issues like poverty and animal rights and want to give their money away to something that will have an impact. Even existential risk has people like Musk and Tallinn funding them. On the other hand, meta seems to only be funded by Good Ventures and only to a limited extent. If you believe that this is important, then earn-to-give may be an effective strategy.
