When it comes to blocking access then it could do but we do know that kids these days are really that wise on how to make use and find out other ways or methods on which on the moment that they do find out or being curious on a certain things then they would really be that definitely finding on how to do it.Its not always for guardian or parents would be taking up the blame because no matter how you do guide them but on the time that curiosity kicks in plus the technologies that we do have today, then it is really that hard to stop it Parental guidance or handling is crucial and as a parent then it's our responsibility to have this thing specially on raising up our kids on which it would really be that relevant and recommended.You can't really be so sure that they would avoid on things but at least we've done our part as a parent.
You're right, sometimes as parents we forget what it's like to be children and we start to act like these, but deep down it's to protect them, only now teenagers, children, have a very high IQ, they find a solution to everything, sometimes parenting is very hard, I still think that the best thing is to make friends with our children, and whoever achieves this is something I admire, for me the danger does not lie in a teenager spending a lot of money, the danger is in getting sick people who threaten them and make them do crazy things, that for me is the most dangerous and precise thing, that is what one tries to protect them.
As long as children are growing they develop more knowledge because they are becoming leaned in the society. So it's not bad for them to figure out the solution of any changes they have. However on one side the parents should be proud that the child is learning fast but most importantly the children should also know that the parents are trying to protect them from gamble harms. As a child no matter the kind of IQ you have you can't be smarter than your parents because they have more experience than you, it's just that as a child is growing the parents are becoming old.
