And here we have another straw man.  No-one is arguing that people do not 
have a right to do such daft things as have been discussed in this thread.  
And whether they do or do not have such a right has no bearing upon whether 
what they are doing is daft.

Indeed, people are even encouraged to daft and damaging things in some cases.
