Isn’t being able to see other people’s wallet assets an invasion of privacy?

Today I learned that I’m able to search up my friends assets on their wallets by simply searching up their wallet address. I realized one of my friends had between 50-60k usd worth of crypto in his wallet, and I really regret seeing this because I feel as if this is an invasion of privacy. Isn’t this a huge red flag for crypto? I doubt my friend would’ve wanted me to know how much he has but it got me wondering if other people check what I have in my wallet. What do you guys think?
