What is the problem with losing so-called 'traditional words' from the English language?

I’m tired of reading articles like this one where a ‘worrying trend’ is reported about how all hell is breaking loose upon the English language due to textspeak or what have you. Is there any proof that we’re using less words (and is that such a horrific problem? language exists to serve us, we don’t exist to maintain a specific amount of words in our language) or is it just people worrying about whatever ‘good old days’ they waste time worrying about? Why do people not see that language is ever-changing, that it’s dynamic and contextual. Many words die out all kinds of reasons and if textspeak is the reason balderdash (!) is no longer used, so be it. This goes along with all of the ‘proper’ grammar paranoia and ‘our kids can’t read, write and etc. anymore’ kind of whining. Well, if your children can’t read and write, blame yourselves. What do you think?
