No, that is not what we gather from the story of Simon Magus. Offering money for the anointing has absolutely nothing to do with helping a pastor financially.
#1, that is not what Paul said: "Let the elders that rule well be counted worthy of double honour, especially they who labour in the word and doctrine. For the scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward. (1Ti 5:17-18) That passage has long been understood as an allowance for the financial support of a pastor or other minister.
The first five chapters of Acts do not make any case at all against paying a pastor or other minister.
One of the hazards of being a bi-vocational pastor is that the pastor isn't always available when he is needed. He is the servant of a secular company that needs him on a regular basis for a job. He isn't free to visit and minister during the week. He barely has time to prepare for Sunday. He has to juggle a church, a family and a secular job, and all are vying for his time. And somewhere in the middle of all of that, he has to find time to sleep.
If he sacrifices time on the job, asks for too many days off for ministry purposes, he will lose that job because his boss needs him on the job and if he can't be there, he will fire the pastor and then the pastor has nothing. So, there are some advantages to taking a salary at the church so that it frees up the pastor to be the pastor and to be a father to his family.
