In a world where you don't own things but can only rent them (and potentially where there is limited competition due to natural consolidation), you may be taken advantage of via high margins that result from an imbalance of power or information between you and the companies you rent from. What starts off as a great deal may quickly become untenable if they raise prices.
Laissez-faire capitalists will tell you that the solution to this is perfect competition. I'll observe, though, that perfect competition doesn't seem to have thrived in many industries. I'd guess that one cause is that no one (particularly investors) wants a business with razor-thin margins.
If you don't believe that consolidation will lead to fewer options and an imbalance of power in more industries, look at the history of today's monopolies. Look also at the advice that investors like Peter Thiel give to startups in books like Zero to One.
