Communication/therapy between traditional in-person sessions.

Completely agree. There must be the same setting as we have in normal sessions. I believe there is a smart solution that satisfies all those conditions (ability to get paid, set limits etc). From my perspective, technological advances will soon change that aspect.

I've had email correspondence with other healthcare professionals. It's part of what I paid for... periodic discussion about issues that came up.

Therapists don't do much to begin with so they can respond to a few emails. If it gets excessive, that's a problem, but then that excess probably points back to a problem with therapy itself.

Therapy tends to destabilize people so therapists need to be at least somehwat responsive, or it's starts looking exploitive and crazy.

I agree with this, especially the bolded part. Sure, many Ts go through extensive training and continuing education, but so do many other professionals that actually provide practical, tangible, directly useful services. I emailed with doctors, lawyers, financial advisors etc regrading the service I paid them for and even more... some of them were quite willing to provide oral support (within realistic limits) as well. I also always try my best to respond to my own work-related contacts promptly and it is really not such a big deal, just normal part of the work. I think many Ts make way too big a fuss around contact and make it sound like they provide something really special, above and beyond, when it is just normal work routine for most people these days, especially those with any private practice. And I think doctors, lawyers, people working in customer service etc put up just as much client frustration and emotion than a therapist. Ts really should not think they are so special or work super hard, need more self-care than the average professional etc... many of them are not even that busy and work much less hours and charge relatively way too much.
