I like the examples you gave, especially the one about tracking goods to fight fake products. That’s a big problem here.
One idea I think would be useful is a DApp for transparent public spending. Every government project and payment could be recorded on the blockchain so anyone can check where the money really goes. It would make it harder for funds to disappear and could increase trust between the people and the government.
Another one could be a land ownership DApp to help verify property documents. That way, nobody can sell the same land to multiple buyers which happens a lot here.
I believe if we start building more of these local-focused solutions, people will see blockchain as more than just trading crypto
