This is not a matter of good or bad, or the absence or presence of ethics. It's a matter of defrauding Google at exactly where their profit is, their cash cow.
To phrase it in another way, if Google wasn't very good at detecting fraud, it would not have been making so much money or becoming such a big company. Billionaires are more likely than not to be absolute misers; the same applies to corporations.
Obviously I'm not condoning clicking on your ads a few times to get the payout. My account got banned and I haven't used adsense since. Everyone uses adblockers anyhow now... But to PERMA ban someone for this small offense (compared to actual fraudsters that use malware to get ad clicks) is insane.
Especially when your company basically controls the internet. I'll repeat what I said before, Google pick on someone your own size.
You probably got automatically banned, it wouldn't be that hard for a program to detect what you described. Browser fingerprinting has existed for years. I doubt anyone at Google is picking on you, specifically.
