It's easy to influence all Joes on the social media platforms virtually all of them use.
> 2. Direct democracy would not follow party lines, there is no need to.
Party line is less of a problem in countries with sensible representative democracies, i.e not FPTP.
> You can have gun rights and abortion rights. You can have social safety net programs and curb illegal immigration. You can be tough on crimes and treat drug addiction as mental issue. You can have higher taxes but lower regulations. You can have higher military spending but no wasteful spending. You can have higher marginal tax rate while having simple tax code.
I completely agree with you here, but like others you only talk about the big issues. Not the small day-to-day operation that must also be handled as well as all the small "boring" issues that face any real government.
> 3. Because any other forms of rulers get disconnected form people as soon as they start ruling.
Representatives are not rulers.
> 4. No "too-big-to-fail" ruler (dictator, king, plutocrat, oligarch, meritocratic, strongman). Entire country doesn't depend on single charismatic person.
I guarantee that if direct democracy was implemented you would have charismatic personalities telling people how to vote on day one. And they would be much better than influencers trying to use reason too.
> 5. It might have been difficult in the past, but in the internet age in USA, direct democracy has less things that would work against it. More information available, more means to communicate available, decent education available.
More information overload. More false information supporting your preexisting views.
> 6. Find best people for the job. Ideas can come from anywhere. Implementer can come from anywhere. You won't get "I implement my idea, not you". "You stole my idea". etc.
Just like today it would be the most charismatic that flow to the top. Perhaps it would be even worse since today only the representatives have to be charismatic. At least their aides and bureaucrats can be ugly and socially inept as long as they are good at what they do.
