Stealing my time and attention. Much more bothered about advertising in my face than IP infringement.

In exchange for a service. It is the way you pay it. You can simply refuse to transact.

What service am I getting when I’ subjected to a billboard that says “get a smooth kitty” with a picture of a Sphinx cat, exactly? (It’s for laser hair removal and is clever but that makes it more annoying because my kids ask me what it means)

My bad, I thought you were talking only about advertising in media.

And mental health.

and my energy (CPU, etc)

Then why do companies claim I am stealing from them when I use an adblocker?

But if viewing ads is a payment method, then you must also understand that showing me ads (without giving me anything in return) is stealing.
