Yes, you could. The last time someone I know spoke to them, the standard enterprise plans started at $5000/mo and got you some very nice freebies. Cloudflare's also announced managed WebRTC APIs (in closed beta) which look promising for creating meeting rooms ala Zoom.us. I imagine, these are already available to tech-shops on enterprise plans.
Though, mux.com is decent too, from what I've heard; for certain workloads, LiveStream and Vimeo might be cheaper.
There's Peer5, PeerTube, and BitTorrent in the P2P space (among many such solutions).
I have never used mux.com (I have used Vimeo, AWS Elemental, and Cloudflare Streams in the past), but they are fairly well-known as the founders created the very popular video.js library. One key thing that differentiates mux.com from others is they're multi-cdn unlike AWS Elemental / Cloudflare Streams, say.
