Why doesn't modern calligraphy simplify Chinese characters?

Calligraphy is a font created by the ancients with a brush because there is no hard pen. If we use modern simplified characters, we will lose our historicity. Furthermore, it is said that the works of modern calligraphers imitate the classics of the ancients not because there is no innovation, but because they don't necessarily know classical Chinese, and they don't need to know the meaning of "Wen", but the meaning of "Zi"! Does the landlord think it is necessary to understand what he is writing when reading calligraphy? If you appreciate calligraphy so much, I'm afraid even the wonderful words will be hindered by complex meanings! Rules are made by people and changed by people! But everything has principles. Perhaps there are many reformers since ancient times, all of whom are people who break the rules. But it is meaningful for them to break through these rules, and the landlord must break through the rules of changing calligraphy fonts. Just for the advanced significance of the times? There are always things left behind in the past, and calligraphy is a historical relic and treasure. Calligraphy is a way for people to preserve history. If it changes, then times will make it lose its original meaning.
