I would disagree and say that bitcoin is indeed for everyone, but some aspects of the infrastructure may be out of reach for some people based on their circumstances.
We know that the billions of people in the world who are unbanked or living in low-income situations will not be able to run their own nodes. That's why we're building the Lightning Network, to provide a reliable decentralized payment system that allows everyone to participate in the bitcoin experience.
It's not required that you personally run your own node to use bitcoin, just that if you have the ability to, you can better verify the state of the network and prove in a trustless way that all of the data is valid. That's what having your own copy of the blockchain allows you to do.
Whether or not you have your own node, you can still download a free app, or use a simple on-chain wallet to store any amount of bitcoin that you can acquire, securely, with your keys backed up offline. As you earn sats over Lighting, you can move them to your long-term wallet for safe storage.
I know can be frustrating to live in a place where you may think you are far behind other parts of the world in terms of economic opportunity, but remember that you are learning about and beginning to acquire bitcoin, and most of the people you see walking around every day still have no idea what it is. Because of this technology, you will be in a position to help yourself, your family, and your community in ways that you might not yet be able to appreciate.
Give it time, keep asking your questions, and learn everything you can. This is something that comes along once in many lifetimes, and you are still very early.
