Does that mean, we will break and not good to scale when rising demand arrives ?
No it just means that the process of scaling up is much uglier than just increasing the blocksize like a lot of these people are trying to claim. Hive nodes are not paying extra money for resources that they don't need. Everyone has to upgrade their hardware for this to happen, and that can be an expense a lot of people don't want to pay.
Thank you for the details clarification.
