just your arguments don't sum up, sorry.
Either you haven't understood how the Bitcoin technology and ecosystem works, or you are susceptible to fears and believes instead of rational arguments. The fact that you mention alchemy when it comes to gold mining seems to support the latter. Alchemy is no real possibility and never was. The things in science fiction movies (and in most mainstream movies anyway) are fictitious. No one can fly with warp speed, no one can hack into a computer just by saying "beep beep" into some phone, and likewise, there is no way some guy can make a homemade or even professionally made device which magically cheats and subverts the bitcoin protocol without anyone noticing it right away.

So your fear is generally ill guided. You should not be afraid about some hypothetical weakness of the system, rather you should be aware of individual people (your business partners) attempting to scam you. Even an ASIC producer could indeed be a scammer, but such an ASIC scammer would have to take substantial risks on his side too, so it boils down to risk assessment for individual business transactions. But the fact there are scammers doesn't allow you to deduce anything about the strength or weakness of the system as such.

The mining of bitcoins and the miners are part of an economic construction, not of an idealistic system. So it doesn't matter if mining "feels good" when you tell about it to outside people. What matters is only if mining fulfils its function within the system, and if this fulfilment of function is guaranteed an perpetuated by a technological and economic mechanism.
