The quick answer is No.
The detailed answer:
1- I'm against adding taxes as the first remedy to every problem we have. This indicates lack of creativity and effort from the government side. Sounds like Democrats in the US.
2- If the government wants to help, let them help the artists by the following:
a. Allow them to rent exhibition facilities for cheaper price in exchange of revenue sharing
b. Gvie them advertisement place on government controlled media (Thank God, we don't have lack of this!)
c. Give artists tax breaks and allow them to accept donations.
