Work: activity involving mental or physical effort done in order to achieve a purpose or result.

I'm not sure what definition you are using or how "the entrepreneur redefines work", but if you think that 'real' work must include lifting heavy things, then you are selling humanity short.

I think he's saying that for some people, entrepreneurship is more about indulgence than discipline, and that discipline is pre-requisite for something to qualify as "actual work".

In the terms of your definition, he's referring to entrepreneurs that are not directing their effort to "achieve a purpose or result" in a disciplined, effective manner. On paper, of course, they all have a purpose or result, but that doesn't mean the entrepreneur is actually working toward it, at least not very hard.

He seems to be expressing the sentiment that many entrepreneurs are of this slacker variety and use entrepreneurship to escape the demands placed on other, "normal" people for their maintenance, not to drive new results or purposes.
