In general I think that nobody would be willing to go far back in time. You don't need YouTube, but would you want to live without it? How about electric lights? Safe drinking water? Flush toilets?
It depends on what your situation would be and where, when you go back in time. Most people in the world today live in absolute misery, so that's not much argument. The enormous abundance of game animals in the past is just one factor which is mostly forgotten today.
In a world without clocks, no electric lights are needed. The safest and highest quality drinking water comes from springs and streams, still today. Flush toilets aren't needed if you live rurally. And so on.
Not to forget, that the less you are used to comforts, the more physically and mentally fit you will be as a person.
