Nobody can predict what will happen or how fast it can happen in the markets. I chose to stay put because I didn’t want to risk missing the bounce if it happened. I took advantage by adding new money instead. It worked well for me. Could I have done better by your method? Possibly. I don’t regret my decision and we’re plenty comfortable.
You have outlined how you are happy to pay taxes that you didn't/don't have to pay. That's fine with me.
I tax-loss harvested in 2008-2009. I tax-loss harvested every single position in taxable accounts that had a loss. I stayed fully invested and even bought more equities. I did not miss any bounce.
For example, exchange Vanguard Total Stock Market Index fund at a loss into Vanguard Large-cap index fund. Or sell Vanguard Small-cap value index ETF at a loss and buy Ishares S&P small-cap 600 value index ETF immediately. At no time was I worried about missing a bounce nor did I change my asset allocation.
Those realized losses have helped me avoid taxation of any realized gains since. That's how tax-loss harvesting works. Successful investors do not have to pay taxes. And my gains far outweigh my losses. They are the same gains everybody else has except I don't pay taxes on them.
And there are other ways to do this. For example, if one has fixed income assets that they can use to rebalance into equities, then they can double up in a losing position and 31 days later sell some shares to get back to what they started with. If they sell the shares with the most losses, then they won't have to pay taxes. Of course, this is a lot more risky than a simple exchange into a similar, but not substantially identical replacement holding.
When one uses index funds, then it is trivial to find a replacement investment that is similar, but not substantially identical, to use when tax-loss harvesting. Indeed, for every position that I buy in my taxable account, I have already chosen a replacement investment in case I would need to tax-loss harvest whatever I bought. One can do the same thing with individual stocks such as sell F at a loss and buy GM if they want to, but I don't think one can expect two stocks to be as similar as two ETFs or index mutual funds.
And I do believe that NOT tax-loss harvesting in most instances is letting the tax tail wag the dog along with falling in the loss aversion trap. Many folks just don't like the extra transactions that they have to put on their tax returns and they also worry about wash sales.
