"They can very easily escape"

On that note any snake could, given the enclosure hasnt been properly locked and adjusted to the snakes needs.When the enclosure has enough locks and weights and contraptions it doesnt make it very easy to escape. However there is still a remote possibility even if you have taken all the precautions etc etc etc, it applies to almost all snakes, not only giants

Its useally not the bite that's fatal, its the coil. When the snake is large enough and your alone is most likely when a deaths occur, but when you own a large constrictor you should take the precaution to never handle it alone, or without enough people. 2 men woudlnt be able to take down a 20 foot burm barehanded . I have a burm and she is only about 9 feet, but I dont take her out without another person, ever. Why take the chance?

Some parents hate snakes no matter how big they are, my aunt for example loves big ones, but hates little ones , my mother hates all kinds . Everyone is different.

With the proper precautions , housing , experience and respect owning a giant can be a very rewarding experience, dont mean to chew ya up but taking care of a giant and keeping it healthy and being smart about it ...isnt much of an easy task.
