What Is the Financial Incentive for a Miner to Use a non-ASIC-resistant Algorithm If Available?

If a non-ASIC-resistant algorithm is available, a miner has a massive financial incentive to use an ASIC because ASICs offer a vastly superior hash rate per watt compared to CPUs or GPUs. This efficiency translates directly to a lower operational cost and a higher profit margin, allowing the ASIC miner to outcompete all other miners on the network.
