It's far harder to change regulations once new technology comes into the market. There is always a delay between introduction and legalization, and sometimes it doesn't happen at all. Remember,the beneficiaries of the old system will be lobbying to prevent progress. For a trivial example, direct manufacturer car sales are effectively banned in many US states. Dealerships are an entrenched and hated third party. They exist out of "concerns" about rural car maintenance. If there had been a law that mandated X percentage of the population must have a way to repair their car within Y miles, that would have been less distortionary. The average American drives something like 13k miles per year, and modern cars tend to not need an oil change for 10k miles or even longer. Tires last for years. Other maintenance is less frequent. Meanwhile in the 60s you'd change your oil every 3k miles. I'm sure in the 20s or 30s you'd have all kinds of maintenance to do This concern about maintenance is obviously not as critical as it was in the 20s and 30s when these laws were created. 100 years of technical progress with little to no legal progress.
