it's theft of the income of the workforce required to make movies. Whole departments receive residuals based on the post box office sales and that income is required to ensure that it is a viable career. That enables talented and safe people to continue making entertainment which in turn provides a better product.

No, it's not. If I pay for a movie, but I then download it from The Pirate Bay, it's still piracy, but nobody loses anything.

I recently went over my media collection and did some conservative guesstimation of my spending over the last 20 years. I've paid over 6 figures to consume various sorts of media.

I have absolutely zero moral or ethical qualms with downloading and/or pirating content I've already paid for. I don't give a flying fuck if the copyright holder doesn't like the means by which I get the content. The studios and copyright lobby and mafiaa are not good faith operators.

Piracy is not theft. Sometimes it's ethical and justified.

I WANT to pay. I want to give a streaming service money to curate, deliver, and maintain a library of high quality content. The industry doesn't want that to be possible, because it interferes with the bad-faith rentseeking games played with royalties and residuals. I'm done playing pretend, and will happily Pirate even new content I haven't paid for.

I will pay when there's the opportunity for good faith commerce. I'll buy discs and files directly where possible.

In your example, getting a third party to provide a digital copy of a good you already own is not theft. I would argue it's a lousy way of doing things, opening you up to many more problems, but it's not theft.

Taking a good or service that you don't own is stealing. That's piracy. That's theft.
