what if these ideas conflict with the interests of the existing pharmaceutical industry and I face obstacles because of that?
Hello there. This is a very noble and good idea, you are admirable for willing to challenge the enemy. As you know it's the enemy behind the "pharma uncontrolled abuse", I mean they overproduce non-needed drugs. Despite some medicines are very needed and may save life, as with everything the enemy corrupts and brings to extremes.
Facing obstacles requires power, I know that on my personal experience. The more powerful you are the more effective you will be against the enemy, good! I think guidance for the Gods is paramount, because they will lead you to situations in which your power is enough to survive and face obstacles that are of the same "size" of your strength, the Gods won't put you in situations you cannot handle or harm you.
This is the part where you know you are protected against harms.
Or (half-jokingly but honestly

) what if something happens to me during my plane trip

? Since these ideas could potentially challenge the pharmaceutical industry’s interests. How should I proceed in this situation?
Despite all of us are protected, and people may think no scratch happens to any Dedicated Soul, indeed some odds, uncomfortable and problematic stuff may happen to us. If we are a big threat to the enemy, they will try to damage us. Also each of us has some problems and negativity in the Planets, so "shit happens" as HPs/Lady Maxine once said.
So it's up to you to stay safe in your battle and take some measures to protect yourself and be careful. This will reduce the risk of being harmed.
Plus the protection from the Gods, you wlll have a good shield and base for being safe.
If the enemy is threatening you and want you dead, it may happen you break your arm instead in a small accident? Yes it may happen. It happened to me more than once but - man - I am safe and alive.
It is not wise to send a warrior to battle saying "nothing can tough you" while this is true in the most part of this sentence, but a small risk still exist for all of us. Nothing deadly, don't worry.
This, based on my life experience, not just plain theory but applied reality.
In short, if you have the means and energy to challenge big pharma, I would do this without hesitation.
Some smaller companies producing herbal medicines, are indeeed a challenge to big pharma. They survived, so why would'y survive you too?
They can also be a powerful force to push you forward, in case you ally with some of them.
Just my 2 cents,
good luck in your good idea!
