Aircraft ownership can be likened to owning a cherished car (or any other item) - you lavish love and attention on it and wouldn't let just anybody drive.
I'm in a syndicate of 5, we all get on well, we've all got quite a few hours and we know the aeroplane. If we were to let an outsider in to fly it on a fee paying basis and he caused damage then we would lose the use of it through somebody else's misfortune. If someone in the group does it then fine, that contingency is covered in the group rules. But if an hours builder did it we'd be left to sort out the problem whilst they went onto the next 'victim'.
So - that's the reason why. Anyone wants to hours build, then rent or buy themselves. No ham fisted newbie is getting their hands on my pride and joy
That's the personal view, now the practicality view. In the UK to do the above the aircraft would have to be on a Public Transport CofA, with the commensurate cost of the additional maintenance. Also the insurance costs would possibly be higher.
Let's be honest - the vast majority of aircraft owners or part owners don't have to or want to rent out their aircraft, because they've got it for
their enjoyment, not to make money out of it - let's face it if you can afford to own or part own you don't need any supplemental useage and income.
