So you could handle something like 1000tx/s, maybe 10.000tx/s or more, if at some day our internet-technology increases to give us an upstream of 1gb/s.
As
@Peter R already pointed out your assumptions shouldn't be correct for a p2p participant.
But even if they were (and the magnitude might be ok):
I don't think a future where there are 1 or 2 datacenter bitcoin nodes in big cities only (for example Gothenburg and Stockholm in Sweden, Munich, Berlin, Hamburg and Cologne in Germany and so on..) is something to be afraid of, rather something to hope for long term. Because that's the point when Bitcoin became a success and grew without restrictions to it's full potential.
We just need good enough distribution worldwide in different jurisdictions to hinder censorship and surveillance.
The way to this point will take some time and we won't have 1000 tx/s tomorrow but I (still..) hope in a few months/years.
Imho that's the way how Bitcoin will become the most important currency and how one will prevent government issued full traceable E-cash. If we ever reach this point we are past the point of no return, that's when governments have to think how to keep Bitcoin in their country instead of how to prevent their people to use it.
Although I've always been more of a sceptic in regards to Bitcoin becoming the next world reserve currency etc. in comparison to other Bitcoiners, I miss the optimism and what Bitcoin really is about these days.
It's all about smart contracts, new fancy offchain solutions and blockchain technology (tm) today. Imho it foremost should be about Bitcoin as MONEY. And how it (still) has the potential to have a huge fucking impact on economies and how we look at money.
Not all this Silicon Valley start up smart solution crap.
Look where it went all the while people saw it as money, as transferable value: We've seen it go from zero to more than 1000 $ in a few years. All without lightning, all without thousands of extra fancy use cases.
*Disclaimer: I'm not against smart contracts (although overrated atm imho) or all the fancy stuff people build with Bitcoin, I think most of it is great.
Sorry for the rant but I really can't believe how pessimistic and narrow-minded Bitcoiners became. Really unbelievable what kind of damage just a few psychopaths can do.
