Moving games and playoffs to neutral sites decreases incentive to buy PSLs.
We know PSLs are very important to league with pressure on teams to get new stadiums financed by PSLs and government money whether it is grants, loans, services (such as land acquisitions) or tax money.
Taking away games decreases incentives for fans and communities to support teams and takes away money allocated to pay for those stadiums.
For an emergency - i.e. snow preventing access to stadium and services (Bills), snow collapsing d0mes (Vikings), hurricane induced flooding (Saints), wildfires (Chargers), unplayable surfaces (Eagles) and ,more - moving a game is understandable although consumers are impacted the most by cost.
