Ahem. MOST books are written for "commercial" purposes, i.e. to sell copies. If the publisher thought it wouldn't sell, they would never have accepted the manuscript, but allowed it to molder on the "slush pile" instead. And on top of that, WHAT IS WRONG WITH DOING SOMETHING TO MAKE A BUCK ??? I thought support of free-market capitalism was a cornerstone of the Conservative Movement. . .
It is a cornerstone of the libertarian movement and the constitutionalist movement. "Conservatives," especially religious conservatives, would place moral issues above commercial considerations. Not that I wish to speak for them, but I think they would support the notion that government limitations on free speech and property are justifiable as a device to prevent society from becoming corrupted by evil.
Within the Republican party there are a number of issues, such as drugs and abortion, that separate the libertarian wing from the religious wing. But without the marriage of convenience, the party could never muster a majority, so they pretty much tolerate each other and unite over their common hatred of liberal ideology.
Get off your high horse....We're not talking economic ideology here, but the intent of authors. Tolkien's books were less a commercial venture than a love of lore and myth to him. Sure, he sold the movie rights to LOTR before his death....The amount he received was something along the lines of $14,000, if memory serves me correctly.
