Is there actually a question in there or are you just stating the obvious? There is definitely an ongoing argument about what the government should have control over in many countries, because one downside with private companies is if they achieve a near monopoly or cartel type operation, then they can be very manipulative when it comes to pricing abuse. Look at railways for example, if they are moving either freight or passengers they can often be integral to the transportation plan for a country but private companies will often try to squeeze all customers as much as possible. On the alternative side, sometimes unions can try to bully publicly owned companies and push it too far, but politicians are too weak to stand up to them which can cripple a country.
Basically stating the obvious, some people just like to get confirmation from strangers, like saying 2+2 is 4, sure you are not going to get much attention because that's boring, but saying like "pineapple does not belong on a pizza" will, and did for a while. OP just tried something similar basically, just stating the obvious and there isn't a question. To be fair to him, this forum isn't "ask any questions you have" for newbies forum, people can share their own opinions and he basically did something like that which we all agree obviously.
Crypto is just a way of us to get together and that is why this place is called bitcointalk forum but we can talk about anything else too, and since this is the economics part of the forum, it means that his post just has to be about economy, and it is about economy and the role of private sector in it, which makes sense.
I agree, private sector is basically the backbone of any liberal nation, I am putting exception to communist nations of course, but there aren't really that many anymore even in China people own companies now, maybe Cuba? I am not sure but most of the world is liberal these days so it is not really that much of a big deal.
