Hello fyrstikken,
You are right. I never thought it was dangerous having your "Wallet" publicly viewable by everyone. This is very dangerous if someone knows how to break into your account and take your money. There must be some way to protect our cryptocurrencies from these vulnerabilities. I think it is the same analogy of not wanting the public to know how much money you have in your purse, wallet, car, home, office or bank. It is private for a reason and that is to keep it safe.
May the steemitforce be with you.
Keep steeming ahead,
