That angle would work if there wasn't so much disagreement about what constitutes lies. After the last few years, I am definitely not interested in having government actors decide for me what amounts to the truth. Personally, I suppose I much prefer a competition of ideas -- and the ability to decide for myself.
I think there's a reasonable argument that part of that disagreement is a result of the hybrid warfare that is being fought over the information and opinions of citizens in many countries. We know about a few of these where hyper-partisan influencers were paid by Russia (or entities closely connected to the Russian government, if you insist on nuances) to spread Russia's viewpoints and attack social cohesion in the US. Is that a competition of ideas?
Facebook and Twitter have in the past banned networks of account for inauthentic behavior. In other words: individuals (and you can probably narrows this to residents or citizens) are allowed to speak their mind and try to convince others of whatever they believe, but it has to be them, they cannot use bots, multiple accounts etc. It's not an easy thing to filter, of course. But pretend that it was, would you agree with that approach?
