Public access tv (in the US at least) is actually a private platform, you do not have the right to broadcast anything you with on it "as long as it's not illegal."
As with newspapers, magazines, radio, social media platforms, etc., the owners public access tv stations are allowed to exercise editorial discretion with regards to what they publish. There was actually a landmark Supreme Court case about it:[0]
Depending on your dictatorship, it will be different everywhere.
In free countries you just broadcast. It's like the right to eat pancakes, it's not specifically regulated. Of course there are rules of what you are allowed to do or not, for example you can't broadcast in specific frequencies because those are licensed and if you like to do that you need to purchase a license. If you broadcast using loudspeakers, you will have regulations on the loudness of it.
The commercial license might come with its own limitations. Depending on your location, you might get into trouble if you take advertisements for drugs or cigarettes or alcohol. You can lose your license over it but your broadcasting equipment wont try stopping you from doing it.
Sure, and anyone who is banned on YouTube can still "just broadcast". Their rights were not harmed in any way.
To borrow your analogy, you may have the right to eat pancakes but you don't have the right to eat at IHOP. You can be banned from every pancake selling diner in town yet you can still eat pancakes. No one has stopped you from eating pancakes.
I can't agree with this one. Due to the different nature of the mediums(radio waves v.s. internet platform) you can't just broadcast because unlike radio waves Youtube will refuse to carry your signal. That's why I advocate for Youtube be impartial to the content and carry whatever the users put in it. If there's a problem with the content, let it be solved by the parties impacted.
Again, unlike radio, with internet platforms each platform is in its own reality. With radio, when you broadcast your signal reaches everyone indiscriminately. On the internet you broadcast into platforms as if they are different universes with different populations.
People forget even TV had public access, which could get pretty ridiculous back in the day.
Your argument is old, tired, and nonsensical.
