The only reason to get an ATPL/CPL is to charge for your skills. (make money). It does not make you a better pilot.
A PPL can have just as much experience and be as professional as an ATPL except they did not sit in the CAAs classrooms learning about how many hosties a 747 needs.
I think a lot of the feedback you are getting is from people who know aviation is expensive and don't want you to waste your money. I'd rent a few jets and Kingairs and talk to the pilots and then do a PPL on a maggoty PA28 then do fractional ownership then I'd probably know enough about flying to either stay at home or buy the right tool for the job.
Good luck with your purchases whatever they may be. They sound exciting. Let us know what happens.
