I shouldn't entertain this, but I'm bored. So here we go.
Assuming the highest implementation of Warren's wealth tax at 6%.
Assuming the figure of $3.6 billion for Snyder's net worth is accurate.
That would put Snyder's tax obligations at $156m at 6%, and $19m at 2%, for a total of $175m/year in wealth tax.
In&Out's revenue in 2018 was about $1b. I'm using 2018 figures because I can't find more recent; they'd have grown since so this is underselling my point, if anything, as the valuation for net worth is current.

Their profit margins are around 20%, according to this;

That means of that $1b in revenue, $200m was profit.
And . . . $200m is more than $175m. Snyder already takes in enough in profits (of which she is the sole beneficiary, as the sole owner) to pay her wealth tax, and still be taking in millions. And we haven't gotten to her salary, her capital gains, or any other revenue generation she might be making outside In&Out (all of which were already included in her net worth, so we're just not including her gains, here).
So she's still be making millions and In&Out would still be expanding just as quickly and she'd be paying her wealth tax just fine. See what happens when you start including a more-thorough assessment of her finances, and don't neglect to include her income streams?
Before you say it, there'd be taxes on that income, sure. But we can't pre-emptively assess what shenanigans her accountants could work out to protect it from being taxed, as we saw in the article in the OP. Regardless, it wouldn't be anywhere
near what you were claiming.
