You can operate your own node (I do). Plus you are not up2date. Trampoline payments were recently introduced, and a client can insert several trampolines. So even if you use a hosted single upstream node, that node can not trace the target. BOLT12 which is currently finalized also hides recipients from invoices.

The thing about layer 2 solutions is, they evolve much faster than the base layer (bitcoin). So dont trust statements that are some years old.
