You seem to be concerned about censorship attacks -- attacks that necessarily involve orphaning work in some capacity -- either orphaning blocks produced by honest nodes, or orphaning (refusing to include) tx-embedded routing work being sent from honest users.
The payout lottery does make censorship costly for all attackers who orphan work, but you'd need to specify the exact attack method if you want a discussion of specific work-orphaning attack vectors. Even nodes with a majority of "routing work" do not have the ability to costlessly orphan work produced by other nodes, so it isn't clear what exact attack you have in mind or why you think controlling a bunch of first-hop routing nodes under different identifies somehow makes these costs go away.
