Yes but if 1000 people a day decided to cycle to work within a few years the government would be losing taxes.
It wouldn't be spending as much on caring for its citizens though, with all the savings from: the reduced number of collisions (where each casualty in a fatal RTC costs in the region of £1,840,000), improved mental health, improved air quality, so fewer premature deaths related to that, better work attendance, etc.
I'll quote now from cyclinguk.org...
"In England, physical inactivity causes around 37,000 preventable premature deaths p.a. amongst people aged 40-79. In 2015, there were 525,000 admissions in NHS hospitals where obesity was recorded as a factor.
In England (2015), over one in five children in Reception, and over one in three children in Year 6 were measured as obese or overweight.
Without action, 60% of men, 50% of women and 25% of children could be obese by 2050 in the UK, at a cost of £10 billion p.a. to the NHS."
