I certainly don't agree with your assertions.
You wrote that demand is always there (higher than supplied by the market), because people like strive to improve their lives.
This is only for the crane business?
If there is a mature market, like most markets for cranes, and there is higher demand than supply then taxes won't stop either the company mentioned or a competitor.
If your imaginary cost-benefit analysis show an increase in trade that doesn't cover the cost of a new crane due to taxes (and only taxes), your imaginary company either doesn't pay taxes (negative EBIT), cannot cover the small interest rate of buying a new crane, the demand isn't much higher than current demand or calculate wrongly. Either way the loss in margin for the crane company is borderline zero.
Secondly, the taxes are spent by government to educate citizens to secure a competitive future workforce, build infrastructure for 'our' crane company to sell it's products, protect it if a competitor steals the other cranes, environment protection, and many other things. These benefits are much higher than a negligent revenue increase from an added crane that only taxes hold back. At least in theory since that is where we are.
