I recommend googling Andreas Antonopolous videos on 51% attacks by nation states.
Re: parallel Blockchain- there are thousands of Bitcoin copycats since 2011. They're either dead or dying. See the top ten list on coinmarketcap over time. Point is that value will accumulate on what everybody agrees on and there's no way somebody's CrapCoin where they own 60% of tokens and dump it on the market will gain traction with it's inherent risks (security, centralization, lack of differentiation etc).
Bitcoiners themselves don't spend using Bitcoin yet but this change is happening as more and more people believe in it as something that holds value and isn't going to 0. It'll take time and I have patience.
