I mean, every home security decision is a tradeoff, right? At one end of the spectrum, you leave your doors and windows wide open for anyone to come and go, and at the other end, you live in a windowless concrete bunker. You just gotta figure out your own risk tolerance to figure out what you're comfortable with.
I like having the light, as well as the visibility of what's going on outside my front door, that I get from having the windows. They are a weak spot in my physical security, but they're not the only weak spot (no, I'm not going to give the internet a complete list of all of them

), and I don't think that in my specific situation getting rid of them would make a huge difference. There are just too many other ways to break in if someone wants to get into the house. So I accept the (what I consider slight) increased risk in exchange for light and visibility (which has its own security benefits).
But everyone has to look at their own situation and decide what is best for them!
I grew up in a VERY old house; it had shutters, that was it. The verandah and the balcony were open. There was no gate in the front porch.
Apparently, when a certain toddler (names will not be named) began displaying a stubborn inclination for climbing (trees, furniture, anything even remotely vertical) the windows got rebars put in to prevent accidents and the front porch was enclosed. We literally only had keys for the iron gates...the doors and windows had old mahogany bars (painted white to match) to secure them at night.
When I moved to the suburbs with my parents, I was confused by all the keys they had. Front, back and side gates and front, back and side doors. The windows in my parents' house (a nice little ranch with three bedrooms, two bathrooms and a terrace in a nice little up-and-coming neighborhood) were the sort used in hurricane-prone areas. My parents didn't put irons bars on the windows until someone broke in through one of them (aluminum...bendy!); before that they got a guard dog (German Shepherd that scared the bejeezus out of everyone), and the creature was drugged by the next set of burglars...cheese puffs with something in them. The dog was re-homed and the bars were installed.
Our house is filled with light...my husband (grew up in SoCal) LOVES windows and sunshine, but there are sensors on the windows (battery-operated in case someone thinks cutting a wire or messing with the wi-fi will knock them out), and if anyone tries to climb in through one of them, they will create a tremendous amount of clatter. I can sit downstairs and look at the garden (Lord knows we spend enough time working on it so we might as well enjoy it from indoor when the mosquitoes arrive in full force!) from one side and the (formerly) lovely tree line that will now obscure a new residential/commercial development on the other.
We have a dog...she only barks when she's outside doing the Twilight Bark with the other dogs; as far as we know, if a prowler shows up, she will point at her treats and say "give me one of those, and I'll ignore you."
I have military training (at the time we used arrows and arquebuses



), but I'm not comfortable with a weapon in the house. I'd rather prevent a break-in.
I am also that neighbor who knows EVERYONE by sight, and can tell if their schedule is off. Call me nosy, but I'd rather know who belongs and who doesn't. I will text people if someone distinctly odd is around. Case in point, a couple of years back we had a guy walking into the wooded area wearing a suit, carrying a backpack. I took a picture and sent it to the neighbor across the way (his mom is alone with the children during the day, and they were toddlers then). Earlier this year, said neighbor sent me a text message: do you remember the "woods guy"? I said yes...he texted back "doesn't he look like the guy they've arrested about the home invasion that resulted in the murder of a teacher?"
He did. He does. I'd rather know even as I enjoy my second cup of coffee watching the birds and enjoying the sunshine on the branches of the trees. I'm not panicky, but I'm vigilant.
