The article I linked to addresses every single one of your objections more succinctly than I can.

Torrey's "seven easy steps" describe Holiness Movement-style perfectionism. It demands a purity and holiness of spirit which cannot be achieved without it as a prerequisite for getting it!

If one can "get the baptism in the Spirit" by attaining Torrey's standard of worthiness without the baptism, what do we need Holy Spirit baptism for? Or conversely, since we cannot achieve Torrey's standard of purity without being baptized in the Holy Spirit, how can such purity be a condition of receiving Holy Spirit baptism?

That is legalism and perfectionism by definition. It flies in the face of grace. It reduces the gospel to mere moralism. It nullifies the finished work of Christ by adding new conditions to the gift of God which He Himself does not require.
