Never is a long time. Imagine trying to conceptualize modern shipping capabilities before the industrial revolution. It is not only that the cost per ton/mile has fallen drastically, but also the amount of purchasing power average people have. Not to mention the entire classes of industry that were created. Costs to get to space will trend downward. Our knowledge of the solar system and it's potential for economic benefit trends upwards. At some point someone will find a way to make money, even if it is a niche application. That early industry will create the infrastructure which will open up other areas of development etc... A positive feedback process.
