Historically Japan would have executed someone like this and that's not an exaggeration there have been examples in the past. Now is that too authoritarian? maybe .
But Johnny Somali (apparently he's Ethiopian by the way so he even lied about that and his real name is Ramsey Khalid Ismael and he really hates people knowing that for some reason so im putting it out there. ) being a public nuisance , disturbing the public constantly and insulting the country constantly and yet nothing can be done about it because he's technically not breaking the law.
Now imagine tons and tons of people behaving like Johnny Somalis/Ramsey Khalid Ismael and creating public chaos and nothing can be done about it cause they are technically not breaking the law.
Suddenly authoritarianism makes more sense
Yessiree. The history of the world is replete with deranged tyrants who were only able to attain tyrannical power by whipping up at least enough of a mob to make it seem like they had the vast majority of the populace on their side (thus justifying their rule as a glorious expression of what Rousseau would describe as the 'general will') & to cow all the opposition they hadn't lynched yet into intimidation. And without that mob behind them, they either can't get into power in the first place, or their bloody works won't survive long after they die anyway.
Whether it's Cleon screaming for ever more blood to be shed in Athens, Robespierre's thriving guillotine business in Paris, Lenin commanding massacre after massacre from Moscow, or the present American establishment justifying their atrocities from DC with the supposed need to defend Our Democracy™. Every single one of these tyrants understood one thing: without the cloak of democracy to sway the mob onto your side, naked force can entrench despotism for only so long (as Oliver Cromwell's Protectorate, for example, demonstrates). But you get enough of the people to participate in their own slavery and to impose chains on others, and you can really build up a killing machine with catastrophic effects that echo for generations.
