When would effective odds be used in limit hold'em?

[JC21]

I'm reading TOP for the first time, and I have a question about effective odds. Rather than calculate the number of total bets in later rounds and add up the final pot, isn't it always easier to just calculate the immediate pot odds? All I'd have to do is compare the immediate pot odds to the odds of hitting my draw on each street. I suppose in no limit, a player could go all in, so the odds of making your hand at the end would be more useful. But in terms of pot odds, what is the point of trying to predict future bets in limit poker?
