If you eliminate types from the model, you avoid dependency and coupling, but you lose out on strong type checking and basic validations (guards) that you get for free from Value Object types. If you don’t expose domain objects as return types, you will need to provide DTOs. If you provide DTOs, there may be accidental complexity in your solution from the extra overhead of the additional types. Then there is also the aforementioned memory overhead in high-traffic applications that is caused by the possibly unnecessary DTOs constantly being created and garbage
