Yes blockchain can survive without crypto for example there are some financial institutions like insturance companies and banks that are actually using blockchain for some service without any crypto.

I concur here. There are corporations using blockchain technology to show chain-of-custody or for security as a defence against hacking. The blockchain can exist in (mostly) controlled environments where the nodes are all hosted by parties interested in a central goal (whether they are all part of the same organization or several organizations all participating in a shared endeavor).

However, I do think on a grander scale, while blockchain as a standalone technology will likely be adopted by businesses as an internal framework or a shared framework with other businesses, I do think cryptocurrency on a blockchain will be implemented on a much bigger scale than it is currently, whether it is Bitcoin that gains global acceptance and use, or whether governmental crypto becomes more widespread.
