Again, this is not a regulative principle argument. Paul doesn’t need to limit us with restrictions as that’s the exact opposite from how the regulative principle works.
You need a positive command to make something an element of worship. There is no positive command to sing the book of Psalms alone. Instead we have positive commands to teach and edify with songs. Without an express command, the only way you could get to an EP position is to somehow argue by "good and necessary consequence". But there is no exegetically necessary pathway to get to EP, unlike for example the doctrines of the Trinity, hypostatic union, or infant baptism. Paul's words more naturally mean to wisely teach with songs. It is the EP position which is adding to the commands of God in this case, and imposing an interpretation that is not required by the context or the general rules of the Word.
