DSLR cameras have been the leading type of enthusiast camera for long enough that the lenses available for them cover virtually every possible usecase.
In order to take images, DSLRs have to move the mirror out of the way of the sensor. That movement creates a distinct sound that is not present in other types of cameras and the sound may draw unwanted attention.
Within a price range of about $1000 USD best point and shoot cameras can sometimes come close to DSLRs and mirrorless cameras in terms of image quality, but they don't offer anything comparable beyond that price point.
A good number of P&S cameras forgo a viewfinder altogether so the only way to compose a shot is by using the LCD monitor on the back of the camera which can be difficult to use in bright light.
