Technique/skill is nothing more than a way to maximize natural attributes.
Therefore, every little bit helps. In a bout between two evenly matched opponents, the stronger will most often prevail.
Why not maximize your chances, provided the law of diminishing returns doesn't kick in? You can become significantly stronger in 30 minutes a day, twice a week. So why not?
Besides, being strong has other health benefits not necessarily directly related to fighting.
