The "intrinsic value" of any futures contract is the current spot value of the commodity it's written on - some futures are simply cash settled rather than delivered.
So if the spot price of gold is $270/oz, the the intrinsic value of a gold contract is $270/oz. If you hold the contract until expiration, you're going to be taking delivery of a pile of gold and having to pay for it. But the contract can also be sold and it's intrinsic value is always the current spot value of gold at that time.
In the case of index futures, "delivery" is a simple cash settlement on the contract based on the underlying index value at expiration - rather than trying to actually deliver a basket of stock to you.
Conceptually I suppose they could now maybe deliver 500 shares of SPY for each emini contract, but SPYdrs weren't around when the S&P contract was created and cash settlement is cleaner anyway.
This is conceptually similar to the intrinsic value of an option. A $10 call option with the underlying stock at $25 has an intrinsic value of $15. The actual value of the premium depends on volatility, time, etc.
Futures contracts carry a premium too - but it's more straightforward than options and there is no strike price involved - it represents the cost of carrying the underlying commodity for the remainder of the contract life.
Example - you buy a December S&P futures contract @ 1130. The SPX is trading @ 1128.50 (1128.50 is therefore the current intrinsic value of the contract and you're paying a 1.50 premium over intrinsic value).
BTW, when you buy a share of stock - you're only conceptually buying an asset - usually you're buying a bet (that someone else will eventually buy it from you at a higher price than you paid). The "intrinsic value" of a stock is its book value (not necessarily the book value shown in stock profiles though - those numbers are very often inflated with worthless "assets" like goodwill - so you'd have to manually compute the net asset value using hard or disposable assets less liabilities to come up with a real book value). Lots of stocks out there with negative book values, so what are you buying when you buy the stock?
OK, some will argue that you have to factor in cash flow (assuming they have a net positive cashflow) and expected growth (which of course would be nothing more than a pure guess). But those might play a role in trying to come up with a valuation of what is a reasonable premium to pay over the company's intrinsic value, they are not part of the stock's intrinsic value.
So when you buy JNPR @ 24 when it has a dubious $2.55/share book value (dubious because their balance sheet has a lot of worthless "asset" value on it), revenue of $3/share, and marginal to negligible net income - what's the real "intrinsic value" you're buying for your $24?
At least with index futures you always know what your real intrinsic contract value is without guessing.
