Harms from the use of the LNT model
The use of the LNT model led to
considerable concerns regarding even very low levels of radiation
adverse effect on public health because LNT model discouraged/blocked study of low-dose radiation for the prevention and treatment of major and currently intractable diseases such as Alzheimer's and Parkinson's diseases and cancer, though evidence supports its consideration for such diseases
Significant reduction of cancers observed following low-dose radiation exposure, but could not be investigated because of the LNT model
considerable casualties, tremendous economic loss, and disruption of normal life due to precautionary evacuations following nuclear accidents, e.g. in Fukushima, but no benefit.
harm to patients due to misdiagnoses/missed diagnoses because of patients/parents refusal of diagnostic studies and doctors not prescribing diagnostic studies, and non-diagnostic imaging studies performed due to misguided dose-reduction efforts.

increased power generation costs due to ratcheting up of radiation safety regulations for nuclear power plants
Note: LNT model, ALARA, and low-dose radiation concerns as well as other factors contributed to the observed increased costs over the years.
barriers to development of underdeveloped countries as low-dose radiation concerns have suppressed development of nuclear power in spite of it being the cheapest, safest, least-polluting mode of energy generation. Lack of power is a major constraint for development.
Some headlines regarding power cuts related to lack of adequate power generation

Considering the major harms caused by the use of the LNT Model, there would indeed be major potential benefits from discarding the LNT model:
