Who said they (those particular "experts"). should be ignored? I will say that their words shouldn't be blindly accepted without question.
Other experts don't agree. Our own military has a policy of 21-day quarantine for troops returning from Ebola-stricken regions. Other African countries have imposed travel restrictions that have helped stop its spread within their borders.
And I did RTFA. Limiting travel doesn't have to mean their interpretation of it (forbidding flights from/to certain places). For starters, I'd restrict visas for non-US naionals from those places, regardless of where their particular flight originated. I'd restrict non-essential travel to those places (medical aid workers would count as essential).
Finally, asking people who have been in close contact with Ebola patients to quarantine if at all symptomatic isn't unreasonable.
