So... no. Not at all.
The reason we are not seeing 150M budget movies coming out of crowdfunding is that right now the market is too small. Its a fledgling industry to directly patronize your entertainers without the profit seeking middleman in between (or at least in the case of Patreon et al that middle man is minimized). As it grows projects like the Blender Open Movie project or all the software being crowdfunded will become more common and more culturally accepted.
On top of that, there is very little organization in crowdfunding right now. Almost exclusively because of the newness of it all - it is untested, and for anyone who is just making a living off patronage now taking a huge risk partnering with other artists to combine efforts to make more complicated media is a huge gamble.
That being said, there are no logistical barriers to it. It is only a matter of time. But for patronage models to take over media production - which they will inevitably do, on the simple premise that the middle men profiteers in between creators and consumers of media only existed when the logistics of distribution required not just money but influence in the industry to even get your product blessed to be sold in limited theaters or stores and are now redundant - will require a substantial cultural shift for consumers. And those kinds of shifts take generations. I think those under 30 are fairly receptive to the idea, but to make it pervasive may require fresh minds open to the idea that need to grow with constant exposure to the concept early on.
Otherwise its just a "neat thing" rather than the cultural revolution it will need to be to finalize the model - abolishing obsoleted IP concepts alongside the cultural expectation to "put money where your mouth is" on the things you want to see made, rather than for the things that already exist and are being artificially restricted by the government.
