Very weak. The sad truth is if I send you some Bitcoin and your wallet (using some third party back end) tells you you received it, you're not insane to just trust it.

Telling people to run nodes largely became a virtue signal as they wouldn't actually use them for anything - giving rise to the whole "economic node" meme.

It's not super terrible because there are enough Umbrels/Start9 people out there who can trivially run Lightning nodes on top of their Bitcoin nodes and electrum servers etc.

But still, the UX of node-less Bitcoining is pretty much fine and it's nowhere near easy enough for us to laugh Saylor out of the room for calling us "Paranoid crypto anarchists" for insisting on it.
