The alternative would be going back to proprietary chargers that can only charge one specific model.
I realize you’re exaggerating but all you’re doing is standardizing on size and shape of the connector. Not the power standards it supports. If your laptop needs 240W PD 3.0 and your car supports 100W QC3 you’re still out of business. If your laptop uses QC3 but needs 12v and the adapter only supports 9v you’re still out of business.
USB is not a standard. It is a collection of standards.
