Yes, but we take precautions with those risks too.

We wear seat belts and have laws against speeding and drunk driving so as to avoid unnecessary car deaths (or injuries). We use sunscreen when going out for long periods in the sunlight to avoid skin cancer and sunburn. etc. . .
Right now, I think we have to have a mask mandate (along with other measures), imho, to control the spread of COVID. It's not just protecting oneself (like wearing sunscreen), but protecting others around you too.
Even then (my state, for example, has a mask mandate), it seems restaurants could still be a danger spot.
Remember this chart?
Restaurant spending (particularly, in-person) is a predictor of lagged COVID cases, while more grocery store spending correlates with lower cases.
I think it's the nature of eating at a restaurant. You have to take your mask off usually to put food in your mouth. You're breathing and talking (with friends/family) and the respiratory droplets spewing out of you can get suspended in the air and circulated through the enclosed AC system. A draft of wind could carry it to the person next to you eating and they catch your COVID, because you're asymptomatic.
Take-out and delivery should be safer (although not 100%). Ultimately, I agree with you, Shopetal, on a certain amount of risks being inherent in all aspects of life. But, I think we haven't really done enough precautionary stuff yet in the U.S. to make me want to go eat out at a restaurant. Over 50% of Americans seem to feel the same way on eating out per the surveys/polls I've been posting.
