Your analogy fails to account for the reality of copying. Had you looked at the pattern of the pants, and proceeded to make your own pair out of materials you rightfully own, then your analogy would be accurate.
You, like the original poster, assume that all infringers that are unwilling to pay, must be all converted to fully paying customers or you will be unable to stay in business.
Impossibly false assumptions:
- all infringers are not unwilling to pay
- all infringers could ever be converted to non-infringers
- all infringers act for the same reason
Therefore, we should break down different sets of infringers:
+U – Those who do want to use the product
-U – Those who do not want the product and only wish to collect it, weird pack-rats
+P – Those will to pay at a lower than existing price point
-P – Those who would never pay, regardless of price point
+M – Those who will use the product repeatedly
-M – Those who will use the product only once
+C – Those who will use all features of the product
-C – Those who will use only some features of the product
+D – Those who will buy products with DRM
-D – Those who will not buy products with DRM, reasons withstanding
And on, and on...
There is much overlap between these sets, and it can be argued that under certain conditions members of +U, +P, +M, -M, +C, -C, or -D can be converted to paying customers, but the conditions for each is not the same. There is no silver bullet to the solution, any attempts at such will only create more divergent sets of infringers.
Now the original poster asked how infringers could ever be considered not harmful to his business. The answer to this is obvious, they are not harmful, in fact they are incapable of causing direct harm because they are secondary effects of law and the business decisions that have already been made. The only harm caused is by the decisions that lead to such effect: high prices increase group +P, DRM increases group -D, etc. The law may also cause direct harm, but this outside the direct control of business, or should be. Wither such actions are moral is irrelevant, they will occur in every system: create draconian laws, increases law breakers, and so on. Decisions must be made that maximize the chances that a particular individual will fall outside the reasons that may drive them to infringe, at least from a business perspective.
Attempts to change law or public perception, may also be a valid if not dubious way of creating a solution, but they require the spending of large sums. Bribery to alter laws to gain yourself monetary advantage over your current situation, is generally frowned upon, also known as lobbying.
So I think this explains the situation: bribe your way to greater entitlements, make better business decisions to maximize your paying user base, or cry about how in a perfect world designed for you, you could make so much more money.
Hope that helps.
