“We don’t have free will but we have the experience of freedom” - Brian Greene

We do things for two reasons: either we have to, or we want to. There’s obviously no freedom in having to do something but we’re not free to choose our wants either. It obviously feels like freedom when you have a desire to do something and then you do it, but what else could you have done?

Also, free will implies there’s someone making a decision. What is that “someone” and where is it?

My personal view is that it’s not so much that we should live as if free will exists, but simply that the concept of no free will is incomprehensible - or even destabilizing - to some people. Being acutely aware of it may not be useful for everyone.
