I doubt it's overnight destruction of the business.
It likely means selling some of their amortized equipment to buy different equipment. They've likely had notice for a long time. Especially if they participate in their government.
Of course if you are a homeowner that equipment will last a lot longer. (home owners buy a cheaper grade of quality in general, so you can't compare lifetimes with pro grade equipment)
I have personally seen such equipment remain in use for 15-20 years. When I was young the lawnmower we used was a monstrous Craftsman that was originally built 20 years prior. It was used year-round for that period for everything from snow removal, lawn mowing, and hauling landscaping supplies (retaining wall blocks and the like).
You would likely be surprised at the level of care and maintenance some small business owners put in.
We are talking about hand held stuff here though. While pros need equipment to last longer than home owners, there is a limit to how much mass they can deal with for something that is hand held.
Many run their business with the tools they can afford. Upon inspection, you would find that many such businesses have little to no resale value to lean on to make such an upgrade.

What percentage of people laborers have the time to actively participate in government? I don't know the answer to this but I suspect it's shockingly small.
Are electric equivalents of the banned gas tools really that much more expensive?
The problem preventing commercial adoption is that if you want commercial user amounts of uninterrupted run time you wind up spending a fortune on batteries.
