Maybe putting the laptop in the data center lets you do the launch. Maybe the launch is a flop because you forgot to advertise it. Maybe you raise series A funding; maybe you don't and the site dies in three months, still happily running on the laptop. Maybe someone decides to re-write the product in a different stack. Maybe the product was wrong and needs to pivot.
A lot of products have shipped and succeeded with absurd hacks in them. Hex-editing the binary to change "EMM386 Memory Error.." to "Thank you for playing Wing Commander", etc.
Most good developers want to pay down technical debt. Most good architects are able to balance business and technical needs enough to know when and how to pay down what debt without spending four sprints renaming variables. It's when you have either dis-functional leadership who refuses to listen to their employees (most likely IME), or architects weak in either skill or constitution who can't or won't stand up the bosses to try to explain to them why we need to spend some time renaming variables.
