If you make all sections require a donation you are probably going to see season ticket sales go down. I've had corner balcony season tickets since the Wayne Morgan years which then they were $99 a season and today they are like $250 now and those are in non-donor sections. I'm sure they will increase the price again on those and if they started to require a donation for all MBB season tickets that may be the thing that would make me consider not renewing. I'm having to relocate my FB season tickets after my 3 year price lock ended and it's a big difference in donor to non-donor pricing there. $200 bump per seat for the cheapest donor sections and looks like they shrunk the number of non donor sections this year too so will be interesting what season ticket sales look like with the increase in donor level pricing along with the ticket and fee increases on top of that. Not everyone can afford donor level season tickets.
If push came to shove and I got priced out of my men's season tickets I'd probably just buy women's season tickets instead then buy some select men's games kind of like I do with the women's tickets now (which BTW are VERY family friendly with the pricing!) You still need to offer some more affordable options if you want to pack Jack Trice and Hilton consistently because with the additional financial asks of the fan base between donor level increases, ticket price increases, and the push to donate to NIL too it's going to get to the point where it's too expensive for your average fan just like it's so damn expensive to take your family to a single NFL/MLB/NBA games these days.
