Critical that the system operates/keeps operating/does not reach an invalid state.
It could be for safety but in general its more to avoid financial damage. Downtime of any kind usually result in huge financial loses and people working extra shifts. This was my main point.

But it this case likely it isn't. The current systen already works with a chain of blocks its just lacks the distributed checking and all that stuff. But "blckchains" aren't some secret sauce in this case it just an way to implement a distributed write-only database with filed proven tech. It can be as lightweight as it any other solution. The consensus part is completely irrelevant anyway because all nodes are operated by one entity. But due to the use case (money/value) of modern DLT ("blockchains") they are incredible reliable by design. The oldest DLTs that uses FBA (instead of PoW/PoS) are running since 9+ years without any error or downtime. Recreating a similar reliable system would be month and month of work followed by month of testing.
Yep, pretty much agreed. Whatever anyone may think if crypto currencies blockchains are essentially a different technology where coins are just 1 application. I'm kind of "meh" on crypto currencies (not anti, just think they need a while more to mature) but trustless consensus is a significant innovation in its own right.
