I think it is interesting that opinions vary widely on this topics.
You are the only one that I repeatedly hear saying that a Raspberry Pi isn't enough. The people I know personally in the Bitcoin community run just fine with Rsapberry Pis - and cpu/ram usage is never a complain.
And 20-30 channels is also something I hear from nobody else. People who advocate self sovereignty sometimes talk around 1 channel. But I guess you are right about "helping the network" with 3-10 small channels is a myth.
You have been endorsing Core Lightning over LND for a long time, haven't you? I hear this more and more often recently.
Anyway, thanks for your work! More opinions and more research is always more good.

I do not endorse any LN implementation. I am just pointing out pro/contra issues for both.
"Self sovereignty" - I think this is a wrong term. Is just sovereignty without "self". You can't be sovereign to yourself... :)
Having your own node for more privacy and decentralization is a different thing from having a routing node. This where many users still don't make the difference.
Running a LN node on a RPi is ok if is a private node. Running a routing node on a RPi is not good because that tiny machine is NOT reliable as per a routing node!
Running a private node with 5-10 private channels is more than enough to do your own LN payments. But running a public node with less than 20-30 channels is useless.

From experience chatting with friends and my own experience, I have heard bad stories from some, and I'd say:
Go with top of the line everything for a RasPi setup, good, large SSD, most RAM you can configure. What I think is not really sensible is thinking it's possible to DIY and use the cheapest configuration that 'technically works'. This is still a cheap setup for a hobbyist ... but it's not that cheap! It's not something a 14 year old can set up with a couple of weeks' pocket money :)
bitcoind especially, and to a lesser extent LN node, plus all the extras people inevitably end up installing ... it's so easy for the hardware just not to be able to keep up.
