I think 100% decentralization is nearly impossible, and what we know as "decentralized" is a myth. It is definitely censorship-resistant by nature due to its architecture, but every network is vulnerable at some point.

What happened to the LBRY network? They announced their official closure in June 2023, citing a court loss and several million dollars in debts. Now, we might say that's because there was someone liable to answer to the SEC and the court, which isn't the case for the majority of blockchain networks. True, but they can seize domains, instruct exchanges to stop trading and facilitating tokens on their platform, and ask mining pools to stop supporting the mining of such tokens. Such actions may lead to a slow death for the network, like LBRY. A network is alive as long as users use the network, host nodes, mine, and trade tokens. If miners stop mining and people stop hosting nodes, the network will eventually die over time.

Every blockchain network node relies on "seeders," which are groups of domains keeping track of network nodes and from which new nodes download data. You don't need to take down every node, just the seeder nodes, to make the network unstable!

Nowadays, due to Bitcoin and cryptocurrencies, everyone thinks that starting your own chain is the only way to make something decentralized, but that's not true. You just need to ensure enough copies of data are circulated on public platforms. Do you know how we decentralize energy? By using solar panels! Similarly, you might have used torrent files, a type of P2P file sharing to download music and video files. That was also decentralization, but the difference was that developers didn't put tokenomics over its real purpose. You don't need some shit coin transaction to be able to send or receive files. So, decentralization isn't something new that came after Bitcoin or blockchain; it was already here.

I'm saying this to explain that when we think about decentralization, we don't need to think we must have a Bitcoin-like network with nodes all around the world to make it decentralized. It's all about data replication on a large scale.
