The argument in the post seems to be the following.
Premise A: You already believe in 1-4.
Premise B: Effective altruism follows from 1-4.
Conclusion: Your own views entail the principles of effective altruism.
But I don’t think the conclusion follows from Premises A and B. Even if effective altruism follows from 1-4, and even if someone believes in 1-4, it need not follow from their whole set of beliefs. They may have additional beliefs that are in conflict with effective altruism (e.g. a strong preference for a certain cause, or perceived special obligations towards a certain group of beneficiaries), and may only be willing to apply 1-4 as long as they aren’t overridden by those additional beliefs. If so, the conclusion doesn’t seem to follow.
I’m not sure about the reasoning in Four Ideas You Already Believe In. The four ideas are the following:
It’s important to help others
People2 are equal
Helping more is better than helping less
Our resources are limited
