If the company's value increases by 4% over the year, and it pays out one of those four percentage points as a dividend and reinvests the other three, you get the scenario you're talking about. (And it doesn't matter how much of that 4% is revenue minus cost of sales and how much is, say, increase in value of its holdings in another company or real estate.) But if the economy grew by 3% and the company's value increased by 4%, your company is doing better than the economy as a whole, and it's because someone else is doing worse. In the US over the last 40 years, a very significant "someone else" here has been the employees — as they have lost bargaining power, they have gotten worse bargains.
It seems like maybe you're saying that the revenues, and therefore the profits, don't count here because they're not part of economic growth, but just part of the ongoing economic activity. But what determines the P/E ratio, which is to say the return on capital (as a reciprocal), across the market? What keeps investors from bidding the market cap of the company up from ten times earnings to a hundred, a thousand, or ten thousand times earnings? It's the availability of other investments that they expect to grow in value at a higher (risk-adjusted) rate. If you can get a 16% annual return on your investment by buying solar panels instead of stocks, then the guy who does that will have 16% more money to invest in more solar panels every year, until either he bids the price of solar panels up (due to limited manufacturing capacity) or he bids the price of electricity down (due to limited transmission grids or electrical demand). The first of those is already happening; the second one should start happening in about 2024, earlier in some areas.
Now, you could argue that there's a difference between this solar panel maniac guy spending 16% of his capital base in solar panels every year, accumulating more and more solar panels and selling the electricity from them to buy more, and GDP growth, because the solar panel maniac is accumulating a stock, while what the GDP measures is a flow.
But note that by the hypothesis that the maniac is investing to get some relatively inflexible percentage return on his investment, he receives a flow of earnings that is proportional to that investment. And that flow is part of the GDP.
