The mining reward is similar to a military budget. The higher the amount, the harder it is for someone to mess with peoples freedom to spend their money.

Currently it is about $10B per year.

The military budget of the USA alone is over $700B per year.

It is a tricky issue. How can we create security from malicious actors without spending much on defense?

How much does the world spend on locks? Probably a lot. It seems we have not found a cheaper way yet.

Maybe proof of stake will be as reliable and cheaper. We will see in a few years.
