Well put. Ditto, say, a game developer. "Find another way" is great and all for games, if you want a bunch of Facebook monstrosities welded into an always-online authentication framework (or equivalent systems). "But you can sell a version with physical stuff that people want" is similarly silly - I'm not a model-maker or a map-maker, I write software and I'm not going to write software if the only way to make a living off of it is to sell tchotchkes. (And, without meaningful copyright, it's easy to duplicate whatever that thing is and sell it as if it were 'official' anyway.)

I'm trying very hard to avoid an ad-hominem, but I wonder how many people who espouse this "everything should be free" mindset actually create stuff and hurt themselves with this argument. Even software developers who strictly write software for other people benefit from copyright in a work-for-hire arrangement.
