In this particular case it doesnt solve this problem.
It solves the problem of the tracker.. Before you needed to trust the middleman by using another authority for trust, like your government given permissions and making inspections.
With the blockchain you can transfer that to the peers participating in the activities themselves.
It's the descentralization of trust. Right now we have to trust several databases from different peers, that no one have access to, and make a big effort if we need for instance know the state of something tracked by those systems.
Blockchain is a hype in a lot of situations, but that doesnt mean it doesnt have some problem domains it can be used to solve..
For me is just a algorithmic tool, like a hash, binary tree or a merkle tree. There are some problem domains where you might consider it as something to be used to solve some particular sort of problems.
Maybe for tracking physical goods it might not even be the best tool, according to the circustances, but it is something to be take into consideration, to solve this particular problem domain.

Assuming you can trust them, which kind of defeats the point. If you trust your supply chain, why do you need a computationally expensive trustless system?
