While of course what you say is true as far as it goes (money can be spent either on repairs or on new stuff), here is a way the broken window fallacy can itself be a fallacy.
If almost all the currency in a society is hoarded by the wealthiest 1% (like kept in the "Casino Economy") and the 1% control the government so it refuses to directly print more currency according to the needs of the 99%, then the economy for the 99% functions as if there were a depression due to insufficient currency in the economy of real goods and services.
The health of an economy for most people (as well as the political health of a democracy) is not just how much currency there is, or how fast it moves, but how broadly the currency is distributed. Many average economic indicators may not reflect this economic depression for the 99% due to currency unavailability -- in the same way that if Bill Gates stepped into a homeless shelter by accident, everyone in the building would on average be a millionaire.
For more on the "Casino Economy" or "Gambling Economy" of abstract finance see the section of Money as Debt II starting around here: https://www.youtube.com/watch?...
In such a circumstance (which is close to the economy we have now), if a window breaks that a wealthy person or the government wants to fix, then some of the hoarded and speculated cash from the Casino economy may be leaked into the real economy of the 99%. This would temporarily alleviate a tiny bit of the ongoing defacto economic depression until the money is sucked back into the ever expanding Casino economy again via interest on debt or other forms of rent-seeking. Someone breaking a to-be-replaced window of a wealthy person or government in such a situation is then engaging in an indirect form of theft. WWII was another example that led to increased government spending and progressive taxation in the USA, although to great human suffering across the globe in other ways.
To be clear, breaking a window that needs to be repaired by the 99% does not have this currency redistribution effect since no additional currency will be moved from the casino economy to the real economy. Then we are just left with the fallacy in its standard form -- not the fallacy in the limiting case of concentrated hoarded wealth.
Of course, in practice, things getting broken only gives excuses for future crackdowns on "terrorists" and the diversion of what little cash is left circulating in the real economy for the 99% into new taxes for a larger security apparatus to protect the windows of the 1%, so ultimately the path of breaking windows is likely self-defeating.
Better options include alternative currencies, local exchange trading systems (LETS), an improved gift economy like via free software and shared knowledge like with Slashdot, improved local subsistence production like via 3D printing or home gardening robots like Farmbot, better democratic processes leading to better government planning, and political change towards a basic income (with the BI funded by progressive taxation and rents on resource extraction or government-granted monopolies like broadcast spectrum use). I discuss those and more options here:
