Nobody is out here arguing that privacy is important because they want to make it easier to get away with things that are immoral or criminal. The importance of privacy is in retaining as much control over what information you share with others as possible, especially with the public at large, corporations, and the government. The information you wish to control is typically the kind that is sensitive in nature: PII; browser history, authentication secrets; what banking institution(s) you use; what accounts you have and their identifiers; financial information (what assets do you have, what are they, and how much are they worth, likewise with debts); spending patterns (where you shop, how often, how much do you spend); political affiliation and activities; religious beliefs and activities; how often do you travel, where do you go, and how do you get there; what is your daily routine/schedule, and how frequently do you deviate from it, etc. The list goes on and on.

Some of that information you might be totally fine with anyone knowing, such as your political leanings or religious beliefs. Others might be deeply uncomfortable with that being shared with just anyone. I assume you'd agree with me that at least some of the information I listed above is unambiguously of the variety that deserves privacy, i.e. you control who has access to it, and when.

Some things that should be generally private (e.g. financial activity), might need to be conditionally shared with certain parties (e.g. the government) - you might be fine with the IRS knowing details about your financial activity for purposes of taxation, but be understandably pissed if you found out that they were then making that information freely available to anyone that asked - because they have taken away your control over that information. I'm not saying that is actually the case, it is just an example.

Lastly, the more information about yourself that is effectively public information (either because you don't keep it private, or someone else has made it public without your consent), the easier it is to uncover other things that you do consider private. If someone can monitor everywhere you go, they can build a picture of you as an individual. Maybe you don't share your religious beliefs with others unless asked, but if someone knows that, e.g., you go to a specific church every Wednesday and Sunday, they now know your specific denomination and that you are more involved than the sort of person that only shows up on Sunday mornings, or only once a month, or only on holidays, etc. That information can be used to target you, either for innocuous purposes like advertising products to you that sell predominantly to that demographic - or for more malicious purposes, like running a scam against you that appeals to your specific beliefs, or in some cases, violence. That may seem unlikely to you, but you may also benefit from not being a minority that is prone to being targeted in such a way - the right to privacy ensures that we retain control over the information that can be used to target or hurt us according to our own risk tolerance.
