> > just run your own guard node that you trust

I guess this approach works fine for an individual, but if everyone has to run their own guard node to be safe, why would anyone connect to your guard node (given it would be risky from their perspective since they aren’t running it themselves).

In other words, if you accept you can’t trust anyone else, why would anyone else trust your node too?

(Edit: Sorry I’m wording it poorly but I hope you get the idea)
