Honestly, piracy doesn't cause lost sales at all.
If you provide a good product, it will actually increase sales even!
Because let's be realistic, there are 3 types of pirates: those who don't have the money needed to buy it at the time, those who are skeptical of the product in question (think censorshit, not enough raw footage available to come to the conclusion that it's actually worth it), and those who are in a region where the product is unavailable (like region locking, or Ruzzians right now).

If you don't have the money to buy something you want, you pirate now, and pay back later when you do have the money.
If you prevent someone from pirating, it doesn't magically spawn money into somebody's wallets, and after a while the person in question forgets the product exists, and just never buys even after they get the money.

Now with rampant censorshit, you better be skeptical of a product or you'll get scammed.
Pirates notably have the superior version for free, so you could pirate, and still buy the non-pirated version if you liked it, or just not buy it and delete it from your computer if you disliked it.

And people in certain regions simply don't have access to it, so they can choose between importing (and depending on the country you live in, you'll have to pay either the postal service, or the government, or both as a punishment for importing something) or pirating, or just wait until it's available in your region, but chances are high that the version in your region is more censored.
In the past it used to be that the last region got the most bugs fixed, but nowadays it's that the last region got the most censorshit.
