What happens if someone say, lives in Texas and suddenly can't purchase basic goods or get basic services because individually businesses decide they no longer want to serve people whom area gay? Should doctors, nurses etc be able to refuse to render service because their patient is gay? What about teachers? The problem with this line of thought (and why we have laws to help protected individuals) is that it hurts a minority of people and imposes a tyranny of the majority. Christians will likely never have to worry about an Atheist shop telling them to pound sand, but an Atheist in a rural area could suddenly have services taken away from them unless they convert. In this scenario they had the freedom to deny the job and move on; but they wanted to specifically make it about their religion. They want the ability to discriminate not on the basis of being picky with their clientel, but specifically so that they can impose their own religious beliefs on others. And that is the core problem of the case; and also why I sadly think the Supreme Court will rule in favor.
