More Bitcoin can survive these attacks, more time it is likely to survive them in future, and hacks and bans are just form of shot that will help network to develop some protection and make users be more careful. To my mind, these frightening experiences are quite welcome as they remove all those with short term interest and leave behind more steady group of long term believers, getting market ready to enter professional step we are entering. After all, panic that you have described has not brought progress to stop, just made system tougher and more global ready.
Welcome or not, it's not important while the reality is such attacks are free to come, you can not prohibit or block them by any means. The thing is what could not kill Bitcoin over years, actually parts of things to make Bitcoin stronger. It's exactly what has happened with Bitcoin blockchain, its adoption over more than 15 years.
Bitcoin has become stronger than earliest years from its transaction volume, trading volume, and other adoption types. It has already passed most hardest tests and survived very well, and it has also gone to one of two scenarios thought by Satoshi Nakamoto.
Right. Otherwise we couldn't have a finite limit of 21 million coins, because there would always need to be some minimum reward for generating. In a few decades when the reward gets too small, the transaction fee will become the main compensation for nodes. I'm sure that in 20 years there will either be very large transaction volume or no volume.
