I’ve heard building mechas is really difficult but there is no problem in building small humanoid robots (Boston Dynamics). So can’t we just upscale them and make mechas this way?

In addition to the Square-Cube law, you also have limits on materials. As you have much higher weights, the torques becomes much higher, the ground pressure spikes a lot more, the heat dispersion becomes more problematic and so on. Also the reason as of why you want to have such a colossus needs to be answered. The rule of cool does not apply to economic realities.

Bigger is not always better :/
