The instruction situation is an economics problem. If you have a teacher-type personality (i.e. like to hear yourself talk), then giving instruction itself is actually rather personally rewarding, and even fun. It continually reminds you of why YOU like gyro flying.
Trouble is, it doesn't pay the bills. Here in the North, where the weather puts you out of commission for six months a year or more, you don't break even on the machine costs (at least if you count the IRS's mandatory depreciation). Never mind actually paying YOURSELF anything per hour. It BETTER be fun at this rate! You also better have a good day job, or a fat retirement setup, to subsidize the whole thing.
As has been pointed out here several times, most FW instructors are "doing their time" towards a better-paying commercial job. They're willing to work for coffee and doughnuts, temporarily. It's the modern form of indentured servitude.
Gyro instruction, OTOH, is not a building block for any other aviation position. For the person doing the instructing, the job stands or falls on its own merit.
Yet, unlike the oil companies, we can't just double our prices and expect the market still to be there.
I think the only way out of this box is the way that some manufacturers are already taking -- affiliate with good instructors and give the customer who buys a machine a deal on instruction. This insures the instructor a higher volume and may make it possible for the instructor to make more per hour, as the manufacturer shares the benefits.
Obviously, such a system can become corrupt. An instructor ideally is the student's "white knight," giving him/her the unvarnished truth about safety and survival in this very unforgiving environment. If the manufacturer has a defective product, the instructor is going to be tempted to soft-pedal the issue for his/her own economic survival.
Travelling to a training center maintained by one of the reputable manufacturers of a sound design is probably the answer for most people seeking instruction. It's not economically possible to have a gyro instructor in every county, or even every state. They'd all starve at once.
