In the longterm, IMHO no. It's a risk one will take, having a free server to host videos for streaming. But google drive has limitations esp. in bandwidth, and your account can get caught from abnormally high consumption of it. That's the risk, getting your account down means your whole site will have broken videos, and you'll need to reupload/repost everything again.
Maybe it's an easy way to kickstart your site when you don't have the budget to pay for a server, but you'll have to move your videos into a proper hosting/server sooner or later as your site grows and that risk of losing the videos becomes more devastating.
