you do have a point, but piracy could be seen as a response to restrictive pricing models and accessibility issues set by media conglomerates. those high prices and regional restrictions can limit people's ability to access content, especially in economically disadvantaged regions, which doesn't really sound fair to me.
you're right it's not a necessity but if someone downloads a movie they wouldn't have purchased otherwise, it doesn't necessarily equate to a lost sale for the creator.
i pirate games because the repacks of some of the AAA games consume less bandwidth when installing and doesn't have DRM that eats my resources in the background. and if it works well, i end up buying it with no regrets. i feel like everybody should have that freedom to do whatever they want.
