No.
Your example was not apples-apples math. When you use faulty logic, you aren't making your point, your a making a point for the opposing view.
Let's correct your example:
---------------------------------------------------------------------------------------------------------------
Math is math.
Purchase two stocks investing $10,000 each.
Stock #1 pays 3% dividend annually.
Stock #2 does not pay dividend.
[NEEDED CORRECTION ADDITION]>> You sell ~ 3% ( an amount equal to the Stock #1 dividend) of Stock #2 every year.
After ten years new technology is developed that makes Stocks 1 & 2 business models obsolete. Stocks tank to penny stocks.
Stock #1 shareholders have received $3,000 in dividends over the ten years.
Stock #2 shareholders [NEEDED CORRECTION ADDITION]>> [-]have received nothing.[/-] have received $3,000 in LTCG over the ten years, and if taxable, only paid tax on the gains.
---------------------------------------------------------------------------------------------------------------
And no, I don't own less ($-wise) of stock #2 because I was selling. If all else is equal, as has been pointed out, that dividend came out of the value of the stock - essentially a 'forced sale'.

I think you need to make a couple of adjustments.
1. Stocks do not pay dividends in percentages. They pay in dollars. After the dividend is paid in dollars (per share), you can calculate the percentage that amounted to by using the closing share price. But companies do not pay out divs out as a percentage of anything. The BOD declares the div in dollars per share. What percentage of share price that turns out to be depends on the share price on the div pay date or sometimes it's calculated on the current date regardless of when the div was paid. That is, based on the last div payment in dollars and today's share price, the percentage is X. This makes it hard to follow your example because you have them paying out as a percentage and then state the share price drops and it becomes a penny stock....... In your example, the divs would have followed the stock price down.
2 When you sell shares to obtain an equal amount of money as the div, you can't do that by a percentage of the shares you own. It would be a number of shares which when multiplied by the market price at the time of the sale = the amount of the div in dollars. You said these proceeds would all be LTGC. Wouldn't the LTCG portion be only the difference between your proceeds from the sale and the price you paid for the stock? That is, you sold a number of shares that when multiplied by the market price at the time of the sale = the most recent div distribution. The proceeds would be partially return of capital and partially LTCG. No?
In the end, as I understand your description, both stocks would have the same "penny stock" market price, but the owner of stock #1 would own more shares because she never sold any. She would have a bigger long term cap loss to declare partially offsetting the pain of paying taxes on the divs over the years. Or am I misreading your example?
And, finally, you been using the term "if all else is equal" frequently. But, with one company paying a significant div and one not paying a div, can this be realistic? Or is it something hypothetical and not likely to happen in the real world? When I look at a start-up or even a so-called "growth" company that's not paying a div and then look at an established div payer, maybe a "cash cow," whose shareholders expect and receive divs, I don't see two companies where typically "all else is equal." Do you? They likely in very different businesses with investor-owners who have different expectations. How could "all else be equal?"
Bottom line, I don't think that with individual stocks the presence or absence of divs is generally the key thing that will determine my happiness with the investment. That's given that the level of or the absence of a div makes sense with the business they are in. (No tech start-ups paying high divs and no cash-cows paying zero divs, etc.)
Funds or ETFs? A different matter with its own set of pros and cons.
