近几年,不断把一些店堂饭馆题匾上的繁体字书法也称为不规范用字。这种现象从推广简化字的意义上看,无可厚非;但如果从书法艺术的角度,则不难发现,在中国文字的书写上是存在着实用性和艺术性这两者之间的差距的,书法的形成,是社会文明的产物。意味着文字从它的使用价值进入了具有欣赏价值的艺术殿堂。同样是写字,书法却要讲求章法结构、布局造型,于点线的疏密枯润处见精神等等。好比刘炳森先生举例过的“厂”字,简写就显得空而薄,当然就不及繁写的字更有利于结构与造型,还有沈鹏先生举例过的“党”、“国”、“团”的繁写,一写就让人感悟到,它比简写的更具备一种力度,一种庄严。这段话支持下列( )观点。

A.从艺术的角度,繁体字有其存在和使用的必要性

B.繁体字不比简体字好

C.繁体字只限于书法家使用

D.店堂饭馆可以任意使用繁体字
