I'm perfectly serious; i want to download a bunch of stupid memes that my account has liked and saved into various groups in my account over the years. They're public photos that shitpost accounts have posted.

Your likes absolutely are your own interactions, and it's no violation of privacy to allow you access to data to which you already have access. You can't like it unless you can view it first. In fact (it's hidden but it's there) you can go back and view all of your past likes on Instagram.

This is not privacy, this is walled garden nonsense. Instagram thinks they own all your curation activity on the site, and they do not.

>privacy rules

Yet those are pictures posted on the Internet, I don't think people have a strong conviction that others can't save them
