Most people wont run their own servers sure, but a large number of people and organisations will (and do). The more meaningful questions are around "how many people do we need to make this work?", there is a limit where the amount of security is good enough (and this is found through adjusting difficulty mining / or reducing block rewards). There is also a lot of work being done on light clients and faster proofs, so we can bundle them into browsers/apps and not rely on third party nodes for messaging/transacting. This would solve quite a few of moxies concerns right away. Alongside this the work being done on rollups shows us ways of facilitating services for others, without them being dependant on it or locked into it. For comparison, signal is great example of cryptography protecting users, but users being dependant on signal. there is no exit- so in critical situations what happens? Thats the kind of power-dynamic people working in crypto are grappling with. This is a hard problem but it is something worth attempting to solve. How can we provide services to users but have them be able to leave with all their assets when then need to (not when its convenient to us who run the servers). I hear a lot from non-crypto people about how they agree with these ideas but you dont need blockchains to do them, but it seems most of the work to do with this is being done in the crypto/blockchain community (look at who is funding/doing the research on zk-proofs/snarks/starks, which can have a much wider impact outside of the crypto space too! => https://0xparc.org/blog/zk-mnist https://0xparc.org/blog/zk-mnist )
