1. Fair point. I suppose a way to circumvent this is to use the dark web, but I would be hesitant to do so because of my own ignorance in the matter. If a country outlaws decentralized crypto and only allows certain government-compliant VPN companies, then you may be in a communist state and should relocate immediately if you can. Luckily this is not yet the case here and hopefully never will be which is why it's so important to educate people on the benefits and uses of decentralized cryptocurrency.

2. I was giving you an example of how VISA is able to handle more transactions than BTC and does so without 5G. You're concern was with traffic.

3. Nodes are deemed trustworthy by the peer-to-peer network (the validating computers).

Wikipedia:

By storing data across its peer-to-peer network, the blockchain eliminates a number of risks that come with data being held centrally.[3] The decentralized blockchain may use ad hoc message passing and distributed networking. One risk of a lack of a decentralization is a so-called "51% attack" where a central entity can gain control of more than half of a network and can manipulate that specific blockchain record at will, allowing double-spending

So if a majority of the network has been taken over, then there can be problems. They estimate 1 million unique individuals mining BTC, so who can possibly take over that many computers at once? I mean I suppose anything is possible, it's just highly unlikely unless we're dealing with quantum computing. That kind of tech is still far off and when they do start using it and if we have not adopted any measures to protect ourselves from it, the entire system would go down, not just cryptocurrencies.

Nothing wrong with being skeptical. It's the centralized crypto that you should watch out for and are being pushed by the NWO. They are not as secure and can be edited/controlled by the centralized authority.
