Application of blockchain technology by solving real world problem

This got me thinking the other day.

As a sysadmin I spend some time taking care and tracking my assets warranties.

Servers, laptops, desktops, switches, access points, routers, mobile phones, list goes on and on.

All of them have service tag that you can use to lookup the details about device and warranty status on manufacturer portal.

If this information would be put on blockchain by manufacturer at the start of asset lifecycle, building and app that can query and pull necessary info for each device would be trivial.

App could be as simple as scan service tag with mobile phone and info about device and warranty are retrieved and displayed on the phone.

There would be no need for each manufacturer to build their own database and open the API for others to retrieve this info. It's great application of blockchain technology.

Now me and my team are using proper tool that automatically gather this and a lot of other info about devices via network (Lansweeper) so I'm not really in need of such solution. But that would still be beneficial for anybody who does have access to tools professionals use.

Why is no one pushing for use cases like this one?

Every day we get new shitty DeFi project or scam token yet rarely do I see a useful real world problem solving application of blockchain technology.
