So we need public spaces so people can gather en masse.
A public demonstration doesn’t need to involve thousands of people. I don’t see any reason for large scale demonstrations either. Mostly such demonstrations are simply a demonstration of force, sometimes with the explicit goal to block and disturb. I think these types of demonstration are only justified if there is no other option left but to use force against the government: when the government uses force, for example by restricting other forms of free speech or by rigging the election.
Actually I had smaller demonstrations in mind, I would count a single person distributing leaflets as a public demonstration.
I want to stress that I’ve said that public places would be one of the last things that I would abolish. I’m all for privatized roads and space, in a free society public space can neither be justified nor is ‘needed’. I also agree that the state should stop building new roads and that all newly privately build roads should be (real) private property. If, for instance, you want to build a road system for new part of a town and do not provide any space where people can meet without any major restrictions, you are free to do so. People who move to your town voluntarily agree to the lack of public space.
But you can’t just simply privatize all existing roads by selling it to the highest bidder because this would force all residents in a contract with a certain company. This problem does not exist with newly build roads, rational people would not want to move into an area where free speech is under major restrictions so the prices would have to be lower.
Personally I do not know any solution to privatize existing roads which does not involve force. Of course the original source of the problem is that the government has built the road by using force in the first place.
And because this use of force harms the communication (which is a prerequisite for argumentation which is the only way to progress to an Objectivist society) I would not abolish government-owned public space until more pressing issues are corrected that do not affect communication.
It would also be one of the first rights I would break when the society falls back into statism and despotism. With that I mean I would ignore the property rights of the owner of the public place if he acts irrational by forbidding me to demonstrate for property rights and my own property rights were violated (for example when my books get burned, my newspaper gets shut down etc.).
If by censored, you mean put down, then you must not have seen Tiananmen Square in 1989.
Well, force is force, whether you intimidate someone or shoot him dead.
Concerning the Tiananmen massacre I think that despite its ultimate failure and the thousands dead the demonstration was a success. China would be in a worse shape today if that demonstration didn’t happen. Unfortunately, due to massive government censorship, today’s many students in China don’t even know for example the ‘Tank Man’ picture.
Can you explain why being seen by those who don’t want to see it is the essential here?
No, I can’t explain that. You can hardly convince those who actively don’t want to see your message / your information. Besides, if you use a passive demonstration - e.g. distributing leaflets - noone is forced to hear or read what you want to say.
What you can do is to make it easier for those are interested in your information but wouldn’t have found you by other means.
Basically it is a form of free (as in ‘free beer’) advertisement. In a free society I don’t see that it is justified or necessary to support such a free advertisement by government force. But when the government heavily taxes you and destroys jobs any democratic control of the government becomes more difficult if not impossible because it needs more time investment for you to communicate with a larger audience.
And why such a thing cannot happen in a private space where lots of people congregate (of which there are bunches)? That’s really what you mean by “public” right?
It can happen if there is private property, yes. It’s just that currently (at least here in germany, I guess the situation in the USA is better) the ‘good’ places (i.e. major roads and places where many people cross) are already taken by the state. Sure you can start a campagin in your backyard, it’s just that it is much less cost-effective.
