This thinking is ridiculous, and doesn't really appear in any other industry. Do you care whether your accountant's idea of an enjoyable Friday night is sitting at home making more spreadsheets? Would you demand that your eye doctor go home and craft her own lenses in her garage for fun?
The comparisons you've made are with non-creative fields. For those I know that work in other creative industries (graphic design, photography, music, theatre, copywriting), they almost always spend a good deal of their free time exploring their passion. If you love doing something, you probably won't be satisfied if the only time you get to do it is under the strict direction of another.
In any case, if there are enough candidates to select from, and you have no better way of determining which are the better candidates, why not choose the ones that code for fun in their free time over the ones that don't? Those candidates almost certainly have a passion for programming while the others it will be harder to tell. Plus those candidates will be constantly learning new skills that I as the employer will benefit from.
