Applying blockchain technology to life is very necessary because it brings great efficiency in various fields. Blockchain technology is a huge breakthrough in the current technology 4.0. I believe that blockchain will be more and more popular worldwide.
It all depends on how and where you apply the blockchain as 'technology'.
If we're purely focusing on corporate solutions to enhance efficiency and profitability, you only need a database structure to get the job done. There isn't any sort of advantage a blockchain grants you over a database. Everyone thinks the blockchain is it because of the hype around it, but when you discard all the hype, there isn't much of value left.
Blockchains are useful when it comes to decentralized incentives such as Bitcoin, because you at all times rely on the chain to remain immutable. If you don't need an immutable chain, there is no need for a blockchain, period.
I don't disagree with your point as I'm telling essentially the same all the time. The advantage of the blockchain technology as a variety of database solutions is that it can work in a trustless environment where no one trusts anyone in particular. The real break-through in this area consists in using asymmetric cryptography for providing consensus, that is which records or entries in this database are considered valid and which should be discarded.
Of course, if you are using an in-house network, there is no advantage of using blockchain as it adds unnecessary overhead in terms of complexity, capacity, and maintenance. When everyone trusts everyone else, which is assumed for in-house setups, you would be better off by using a conventional distributed database.
