Thou shall not trespass. Pretty straight forward.

To enter into the property or life of another with intent to do damage or make unauthorized changes is criminal trespass. (This is not the same as do not enter, which is a civil matter.)

Prayer is will and will is the exercise of force. To pray for another, any other and for almost any reason including what one thinks should be, without the express consent of that other is to enter into that person's life with intent to force unauthorized changes which is damage. This action is criminal trespass, plain and simple, and is sin in view of the Law which says thou shall not trespass. No attorney will touch the case, unless you pay for services up front.

Give us this day our daily bread... indicates that those to whom Christ was preaching had a nasty habit of trespassing on a daily basis. One might wonder if that has changed.

The admonition to pray for one's enemies is plainly self defense. A pretend enemy does not count.

The Lord commanded don't do it and Christ commanded do onto others as you would have others do onto you. There is simply no license to trespass, preachers, evangelists, experts and other such not withstanding. To trespass in the Name of Jesus just because one can is just straight up Duh!, even if it does make one feel like God when no-one else is looking.

Maybe it's just me but I feel safer around firearms than I do around prayers.
