As a DPC, I do believe you can still save money even when you intentionally decide to pay the 'share cost of the ACA' ( aka, penalty for not enrolling in ObamaCare), be it 1% or 2.5%; and based on your overall circumstances.
It is a fact : if you do not intentionally look for the facts, very few people will ever give them to you.
I encourage you to Read his book where Sean Parnell explains how you can do it. Get the facts, get informed. Learn your pros and cons , analyze data based on your circumstances and be a good consumer.
Hope it helps.
