A truly democratic organization can never be centralized. Because centralized means only a limited number of people or entities taking all the decisions (federal government for example). What we are talking about is a decentralized lobbying group, which will be spread out across multiple countries. I will give you a recent example. In 2018, the financial secretary of India (Subhash Chandra Garg) came up with his stupid idea of jailing anyone having possession of cryptocurrency up to 10 years. The finance minister announced about implementing this plan in 2020, and the bill was listed in the parliament website in 2021. There was a huge campaign in social media campaigns such as Twitter against this bill, and finally the saner members of the government decided not to proceed with the bill in its present form.
