Do Man-Made Rules Make You Holy?

Is it possible to obtain holiness by obeying a list of man-made rules?

Col 2:20 Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations--
21 "Do not touch, do not taste, do not handle,"
22 which all concern things which perish with the using--according to the commandments and doctrines of men?
23 These things indeed have an appearance of wisdom in self-imposed religion, false humility, and neglect of the body, but are of no value against the indulgence of the flesh.

Paul explains that these man-made rules only appear to have wisdom, because they cause you to sacrifice. But they do not improve your flesh or keep you from sin.
