It doesn't affect me at all, but even though I live in a city of about 250,000 people bike theft here is not a common event. When I commute to work I take the bike into my office so it's a non issue at work, but when I go camping I lock the bike with a thick cable, which are the easiest to cut, around a park bench/table to my bike and I don't worry about it. If I'm riding and need to stop into a store I'll either take the bike inside with me or if that's not allowed park it in front a window so I can see it at all times.
At home the bikes are kept in a locked garage and my three best bikes have a cable lock going through them, again an easy lock to overcome but it's just about slowing them down while the silent alarm is triggered and my neighborhood roaming security car is doing rounds might see them. If they get into the garage they're just going to snag one or two of the unlocked bikes, or snag some of my tools, and run.
In today's world with the advent of battery powered angle grinders, no lock is safe to protect your bike with for more than a minute. And the insurance policies that some locks have are completely useless at paying you money for your bike, if you're lucky you might get a free replacement lock, woohoo!
