A tree in the wrong position is just a weed the same as any other plant. We're cutting down literally 100's of trees on our 5 acres, all self seeded sycamore and elm. most are small up to 8inches or so but one that needs to come down is over 2foot thick. It's most certainly a weed, it's even grown up through an old building it is in a terrible position and casting shade all over my vegetable area and of course since it's a sycamore it's happily replicating itself everywhere.
Annoyingly we have to cut down 20 oak trees that the previous owner planted as a windbreak, for some stupid reason he picked oaks and then planted them 15ft from the barn they are already starting to overhang it after less than 20 years. We've also planted several fruit and nut trees in appropriate places, there's a horsechestnut I am considering murdering and another sycamore than needs to come down but that needs planning with the highways department as the road will need shutting when it is dropped.
So cut it down and plant something somewhere else or if you have no space, donate to a charity that plants trees if that will help you with it.
