Why Does the Number of Required Confirmations Increase with Transaction Value?

The number of required confirmations increases with transaction value because the financial risk of a double-spend attack also increases. For a high-value transaction, the economic incentive for an attacker to attempt a chain re-organization is higher.

Requiring more confirmations exponentially increases the cost of a successful attack, making it economically irrational.
