If it's just software running locally, you don't have common data with global consensus on updates.

If you have the common data, it's on a central database and the developer is paying for it.

Blockchains give you the common data without the developer paying.

This doesn't remove cost. It just imposes it on the owners of blockchain nodes, which presently don't charge anything because crypto coins shooting through the roof means they can pay for running the node by just holding coins. This can't stay the case forever. Pushing cost somewhere else doesn't remove it.

I don't think anyone here argued that blockchains are totally free to run, just that developers don't have to pay. Mainly the costs are paid by users, who pay fees to miners for running their transactions.

You don't have to run a node to hold coins. A piece of paper can do it.
