They aren't mutually exclusive.
It's true that both consumers and investors may buy a product, but an investor does so with the expectation that it will
appreciate in value. A consumer purchases a product for use, based on an assessment of its utility compared to its cost, with any eventual appreciation being incidental to the purpose of the transaction.
I'd be interested to see how you feel someone could expect an LEP to appreciate in value over time. Note, getting more updates than the cost of the LEP is not appreciation, nor is getting more updates than you thought you'd get at the time the LEP was bought. In those circumstances the LEP will certainly represent better value to the individual than they anticipated it would at the time of purchase but that's because their expectation at the time of purchase was inaccurate, not because the item has any more intrinsic value that it did at that time. The LEP was always worth the cost of all potential future updates.
As for kickstarters, simply backing a kickstarter isn't in any way an investment in the company because there is no transfer of equity, in fact that is specifically prohibited by kickstarter's t&cs. All that you will ever receive is the defined benefit stated at the time the transaction was undertaken; it's essentially a group purchase scheme with a caveat that unless sufficient people agree to purchase in advance, the product will not be made available for sale to begin with. I know people think of it as investing but it isn't. It's a purchase. The fact that the product would not get made without those transactions does not make them investments.
