Meanwhile, India still doesn't have Lowes or Homedepot.

Quality and verity is missing in superglues, resins, and other stuff which can found in hardware store.

Amazon doesn't fill this space.

Didn't quite quite get your question! Can you elaborate?

I mean India has no way to order screws/bolts of specific size online.

Amazon doesn't serve this market. Can you believe, we can't buy a pulley online in India?

India needs MacMaster Car and HomeDepot/Lowes equivalent. Amazon is unlikely to serve this niche.

It's actually billion dollar market and no one is entering this space for now.

How can Indian entrepreneur/makers create prototypes if they can't source the correct parts they needs?

In big cities, there are some niche shops from where you can source the parts but they are not available everywhere.
