Reasons the Catholic Church bans any method of birth prevention, and denying marriage by priests

For many years, I've thought the Catholic Church wanted to ban any form of a barrier to giving birth for it's own benefit in ancient time. I think it wanted to increase the number of members in their churches to increase their power, control, wealth and land to protect themselves from high death loss due to rampant illnesses.

Its the same reason they do not allow priests to marry to avoid the earlier practice for married priests to give the church property to their families when they died, which reduced the wealth and property of the church.

It's unfortunate the Church continues to base it's beliefs based on ancient conditions.
